| CVE-2026-92516 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix offset warn check for bpf_res_spin_lock Sashiko pointed out correctly that the case statement for BPF_RES_SPIN_LOCK incorrectly checks offset for BPF_SPIN_LOCK. Fix it by checking res_spin_lock_off instead. | ||||
| CVE-2026-92520 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Zero queue and stack outputs on lock failure Queue and stack pop/peek helpers accept an uninitialized output buffer because the verifier expects the helper to initialize it. The empty-map error path clears the buffer, but a failed lock acquisition returns -EBUSY without writing it. Clear the output before returning -EBUSY so BPF programs cannot observe uninitialized stack contents after a failed helper call. | ||||
| CVE-2026-93065 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs The loop counter 'count' was declared as u8 while num_pc is u32. If firmware advertises more than 255 PC entries the counter wraps back to zero and the loop never terminates potentially causing an infinite loop or reading past the allocated pc_data array. Change the declaration to u32 to match num_pc. | ||||
| CVE-2026-89881 | 1 Linux | 2 Kernel, Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: rtl2832_sdr: use vb2_video_unregister_device() on remove to fix DMA leak rtl2832_sdr_remove() runs on USB disconnect and clears dev->udev to NULL before any pending streaming teardown has run. When user space later closes its file descriptor, vb2 calls rtl2832_sdr_stop_streaming() which in turn calls rtl2832_sdr_free_stream_bufs(). That helper releases each coherent buffer with: usb_free_coherent(dev->udev, dev->buf_size, dev->buf_list[dev->buf_num], dev->dma_addr[dev->buf_num]); usb_free_coherent() returns immediately when its dev argument is NULL, so every DMA stream buffer that was live at disconnect is silently leaked. The URBs allocated in rtl2832_sdr_alloc_urbs() outlive the device for the same reason. The rtl2832_sdr driver uses vb2_fop_release() in its file_operations, so replace video_unregister_device(&dev->vdev) with vb2_video_unregister_device(&dev->vdev) and move it before clearing dev->udev. vb2_video_unregister_device() releases the vb2 queue, which synchronously runs rtl2832_sdr_stop_streaming() if streaming is active, so URBs and coherent DMA stream buffers are freed while dev->udev is still valid. vb2_video_unregister_device() locks vdev->queue->lock (vb_queue_lock) internally, and stop_streaming() locks v4l2_lock, so the previous outer mutex_lock(&dev->vb_queue_lock) / mutex_lock(&dev->v4l2_lock) pair around the unregister sequence would self-deadlock and has been removed. A short v4l2_lock critical section around dev->udev = NULL remains so any ioctl path that still holds the file descriptor sees coherent state.

| CVE-2026-93164 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: uprobes/x86: Move optimized uprobe from nop5 to nop10 Andrii reported an issue with optimized uprobes [1] that can clobber redzone area with call instruction storing return address on stack where user code may keep temporary data without adjusting rsp. Fixing this by moving the optimized uprobes on top of 10-bytes nop instruction, so we can squeeze another instruction to escape the redzone area before doing the call, like: lea -0x80(%rsp), %rsp call tramp Note the lea instruction is used to adjust the rsp register without changing the flags. We use nop10 and following transformation to optimized instructions above and back as suggested by Peterz [2]. Optimize path (int3_update_optimize): 1) Initial state after set_swbp() installed the uprobe: cc 2e 0f 1f 84 00 00 00 00 00 From offset 0 this is INT3 followed by the tail of the original 10-byte NOP. After a previous unoptimization bytes 5..9 may still contain the old call instruction, which remains valid for threads already there. 2) Rewrite the LEA tail and call displacement: cc [8d 64 24 80 e8 d0 d1 d2 d3] From offset 0 this traps on the uprobe INT3. Bytes 1..9 are not executable entry points while byte 0 is trapped. 3) Publish the first LEA byte: [48] 8d 64 24 80 e8 d0 d1 d2 d3 From offset 0 this is: lea -0x80(%rsp), %rsp call <uprobe-trampoline> Unoptimize path (int3_update_unoptimize): 1) Initial optimized state: 48 8d 64 24 80 e8 d0 d1 d2 d3 Same as 3) above. 2) Trap new entries before restoring the NOP bytes: [cc] 8d 64 24 80 e8 d0 d1 d2 d3 From offset 0 this traps. A thread that had already executed the LEA can still reach the intact CALL at offset 5. 3) Restore bytes 1..4 of the original NOP while keeping byte 0 trapped and byte 5 as CALL. cc [2e 0f 1f 84] e8 d0 d1 d2 d3 From offset 0 this still traps. Offset 5 is still the CALL for any thread that was already past the first LEA byte. 4) Publish the first byte of the original NOP: [66] 2e 0f 1f 84 e8 d0 d1 d2 d3 From offset 0 this is the restored 10-byte NOP; the CALL opcode and displacement are now only NOP operands. Offset 5 still decodes as CALL for a thread that was already there. Tthere is only a single target uprobe-trampoline for the given nop10 instruction address, so the CALL instruction will not be changed across unoptimization/optimization cycles. Therefore, any task that is preempted at the CALL instruction is guaranteed to observe that CALL and not anything else. Note as explained in [2] we need to use following nop10: PF1 PF2 ESC NOPL MOD SIB DISP32 NOP10: 0x66, 0x2e, 0x0f, 0x1f, 0x84, 0x00, 0x00, 0x00, 0x00, 0x00 -- cs nopw 0x00000000(%rax,%rax,1) which means we need to allow 0x2e prefix which maps to INAT_PFX_CS attribute in is_prefix_bad function. Also changing the uprobe syscall error when called out of uprobe trampoline to -EPROTO, so we are able to detect the fixed kernel. The optimized uprobe performance stays the same: uprobe-nop : 3.129 ± 0.013M/s uprobe-push : 3.045 ± 0.006M/s uprobe-ret : 1.095 ± 0.004M/s --> uprobe-nop10 : 7.170 ± 0.020M/s uretprobe-nop : 2.143 ± 0.021M/s uretprobe-push : 2.090 ± 0.000M/s uretprobe-ret : 0.942 ± 0.000M/s --> uretprobe-nop10: 3.381 ± 0.003M/s usdt-nop : 3.245 ± 0.004M/s --> usdt-nop10 : 7.256 ± 0.023M/s [1] https://lore.kernel.org/bpf/20260509003146.976844-1-andrii@kernel.org/ [2] https://lore.kernel.org/bpf/20260518104306.GU3102624@noisy.programming.kicks-ass.net/#t | ||||
| CVE-2026-93166 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: debug: fix off by on in rtw89_ppdu_str() This > comparison should be >= to avoid an out of bounds access. | ||||
| CVE-2026-92495 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Clear VM_MAYWRITE on DBR/toggle page mmap bnxt_re_mmap() rejects VM_WRITE for the DBR_PAGE and TOGGLE_PAGE mmap flags, but a read-only mapping can still retain VM_MAYWRITE. nd later be upgraded with mprotect(PROT_WRITE). This can bypass the write check that only runs at mmap time. Clear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page branch, matching the existing policy that userspace writes are not expected for these pages. | ||||
| CVE-2026-92478 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Validate connected lane counts The connected lane count is used by TX equalization code to index arrays sized by UFS_MAX_LANES. Reject zero and out-of-range RX or TX lane counts before they can be propagated. | ||||
| CVE-2026-90327 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: phonet: pep: do not write beyond optlen in getsockopt pep_getsockopt() clamps the reported length to the caller's buffer with min_t(), but then stores the value with put_user(val, (int __user *) optval), which always writes sizeof(int) bytes. A getsockopt() call with an optlen smaller than sizeof(int) thus reports the clamped length yet writes a full int, one to three bytes past the user buffer. Write the value with copy_to_user() bounded by len, so at most optlen bytes are copied, matching the length reported back to userspace. | ||||
| CVE-2026-90197 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: haptic: don't write an uninitialized value to unhandled usages fill_effect_buf() initializes value only for the four haptic usages handled by its switch, but writes it to field->value[] for every usage. An unhandled usage can therefore receive either an uninitialized value or one left over from the previous usage. hid_output_report() then serializes that value into the effect's report buffer. Skip unhandled usages instead. This also matches switch_mode(), which only updates fields it recognizes. Found with Clang's -Wconditional-uninitialized. | ||||
| CVE-2026-90206 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nvmet: fix max_qid race between configfs and controller allocation The function nvmet_subsys_attr_qid_max_store() can race against nvmet_alloc_ctrl() when a subsystem's max_qid limit is modified. Suppose max_qid is currently 64. If nvmet_alloc_ctrl() executes: ctrl->sqs = kzalloc_objs(struct nvmet_sq *, subsys->max_qid + 1); and at this exact point, a userspace process changes max_qid to 128, nvmet_subsys_attr_qid_max_store() will set the new max_qid value. It attempts to delete active controllers to force a reconnect, but the new controller won't be deleted because it hasn't been added to the subsys->ctrls list yet. nvmet_alloc_ctrl() then proceeds and adds the new controller to the subsys->ctrls list. Later, when nvmet_install_queue() is called, it will see max_qid set to 128, but the memory allocated for sqs is only sized for 64 entries. This results in a KASAN out-of-bounds warning and potential memory corruptions. Fix this by protecting the queue allocations and list insertion in nvmet_alloc_ctrl() with down_read(&nvmet_config_sem). Because nvmet_subsys_attr_qid_max_store() acquires down_write(&nvmet_config_sem) to modify the attribute, this safely prevents the configfs writer from modifying max_qid during controller creation. Copy the max_qid from the subsystem to the controller's structure during the allocation; ctrl->max_qid never changes as long as the controller remains in LIVE state, so this will prevent similar race conditions. | ||||
| CVE-2026-92580 | 1 Wwbn | 1 Avideo | 2026-09-19 | 8.8 High |
| In AVideo through 29.0, the CloneSite plugin is vulnerable to stored OS command injection. In plugin/CloneSite/cloneClient.json.php (line ~270) the stored SSH password is substituted into the command string `sshpass -p '{password}' rsync ...` with a plain str_replace and no escaping, so a single quote in the password breaks out of the quoted word and injects arbitrary shell. The password is written through the admin-only endpoint objects/pluginAddDataObject.json.php, whose only CSRF defense (isUntrustedRequest()/forbidIfIsUntrustedRequest()) is a no-op when the request source appears to be loopback — as happens behind a same-host TLS-terminating reverse proxy with $global['trustedProxies'] unset — or when an attacker-controlled application is co-hosted on the same hostname; on HTTPS the session cookie is issued with SameSite=None, so a cross-site POST carries it. An unauthenticated remote attacker can therefore lure an authenticated administrator into planting a malicious password (and an attacker-controlled cloneSiteURL), after which the plugin's documented crontab entry executes the injected command with no further administrator action, as the crontab owner (commonly root or www-data). Exploitation requires the CloneSite plugin to be enabled with the documented crontab installed and one of the above CSRF channels; default single-process Apache deployments are reported as not CSRF-exploitable. This is a residual sink of CVE-2026-41304. The issue is confirmed at master HEAD (8963b6a1); no patched version is available. | ||||
| CVE-2026-93019 | 1 Tonycoz | 1 Imager | 2026-09-19 | 9.1 Critical |
| Imager versions before 1.036 for Perl exit the process reading a TGA with a colour map length of 32768 or more in tga_palette_read. The reader unpacks the two-byte colour map length into a signed short, so a length of 32768 or more becomes negative. tga_palette_read() casts that value to size_t and asks mymalloc() for a size near SIZE_MAX. The allocation fails and Imager's allocator calls exit(3). Reading an attacker-supplied file through Imager->read() triggers an uncatchable exit. | ||||
| CVE-2026-54634 | 1 Hamlib | 1 Hamlib | 2026-09-19 | 7.3 High |
| Hamlib is a ham radio control library for radios, rotators, and amplifiers. Prior to 4.7.2, the unauthenticated rigctld send_raw command on TCP port 4532 reaches rigctl_send_raw() in tests/rigctl_parse.c, which writes a NUL byte at buf[buf_len + 1] outside its 200-byte stack buffer, and rig_send_raw() in src/rig.c, which copies reply_len - 1 bytes instead of the actual nbytes received. A remote client can send the CR terminator with a short payload to trigger both flaws in one command under the default no-password configuration. The out-of-bounds write can crash the daemon or corrupt adjacent stack memory, while the oversized copy can return up to 198 bytes of uninitialized stack data to the client. This issue is fixed in version 4.7.2. | ||||
| CVE-2026-90134 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ntfs: fix kmap_local_page() usage in compress Several compressed I/O paths discard the address returned by kmap_local_page() and later access or unmap the page using page_address(). This is invalid for highmem pages, and local mappings must also be unmapped using the address returned by kmap_local_page(). Map each destination page in ntfs_decompress() only while producing the current sub-block. Use memcpy_from_page(), memcpy_to_page(), and memzero_page() for the other page accesses. Remove unnecessary local mappings from ntfs_write_cb(), where pages are accessed through the vmap() mapping. | ||||
| CVE-2026-59181 | 1 Academysoftwarefoundation | 1 Openimageio | 2026-09-18 | 6.1 Medium |
| OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted cineon file can supply a numberofelements value greater than the format maximum of eight. cineoninput::open() uses that unchecked value as the loop bound while filling the fixed strings[8] array, writing pointers beyond the stack buffer and into adjacent state, resulting in memory corruption and denial of service. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), numberOfElements, and strings[8], which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1. | ||||
| CVE-2026-84408 | 1 Qualitysoft | 3 Qnd Advance, Qnd Premium, Qnd Standard | 2026-09-18 | N/A |
| QND contains an improper access control vulnerability in a named pipe, which may allow a local attacker who is logged in to a Windows PC where the affected product's client is installed to execute arbitrary commands with SYSTEM privileges. | ||||
| CVE-2026-20283 | 1 Cisco | 1 Identity Services Engine Software | 2026-09-18 | 6.5 Medium |
| A vulnerability in the IPsec Open API endpoint of Cisco ISE could allow an authenticated, remote attacker to inject arbitrary commands on the underlying operating system. This vulnerability is due to insufficient validation of user-supplied input in IPsec Open API calls. An attacker could exploit this vulnerability by sending crafted input to the IPsec Open API endpoint on an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system. To exploit this vulnerability, the attacker must have valid administrative credentials and the node must have more than one network interface, one of which must be configured as an active IPsec tunnel. Note: For CVE-2026-20283, Cisco has assigned a Security Impact Rating (SIR) of High rather than Medium as the score indicates. The reason is that it is easy to get to root from the achieved privilege level. | ||||
| CVE-2026-84071 | 1 Ibm | 1 Guardium Data Protection | 2026-09-18 | 7.2 High |
| IBM Guardium Data Protection 12.2 is vulnerable to OS command injection in the Universal Connector plugin upload functionality. A privileged authenticated attacker can provide a malicious filename that is incorporated into a shell command executed by the application, potentially resulting in arbitrary command execution with root-level privileges. | ||||
| CVE-2026-54627 | 1 Happyseafox | 1 Sail | 2026-09-18 | 9.8 Critical |
| SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. In 0.9.10 and earlier, psd_private_sail_pixel_format() in src/sail-codecs/psd/helpers.c resolves a one-channel PSD in Bitmap color mode to SAIL_PIXEL_FORMAT_BPP1_INDEXED without requiring the file depth to be one, so the pixel buffer uses one-bit rows while sail_codec_load_frame_v8_psd() in src/sail-codecs/psd/psd.c accepts depth == 8 and writes one attacker-controlled byte per pixel. Loading a crafted PSD through sail_load_from_file() or sail_load_from_memory() therefore writes beyond each heap row, causing memory corruption, a reliable crash, or potential code execution. This mode/depth mismatch is distinct from GHSA-rcqx-gc76-r9mv and GHSA-wcj8-hxxf-pq2c. This issue is fixed in version 1.0.0. | ||||
