| CVE-2026-98037 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject untrusted allocated-object pointers When the final RCU read-side critical section ends, a local kptr is demoted to PTR_UNTRUSTED but retains MEM_ALLOC. The pointer may be NULL or may refer to an object whose lifetime is no longer protected. type_is_ptr_alloc_obj() nevertheless recognizes any PTR_TO_BTF_ID with MEM_ALLOC as a live allocated object. In particular, a refcount-only local kptr never carries NON_OWN_REF, so it still passes the bpf_refcount_acquire() argument check after RCU protection ends. The kfunc can then dereference NULL or stale memory. Make type_is_ptr_alloc_obj() reject PTR_UNTRUSTED pointers. Since type_is_non_owning_ref() is based on the same predicate, graph kfunc arguments obey the same live-object requirement. Fault-protected reads of the demoted pointer remain valid: writes are already rejected, and read fixups use bpf_may_fault_on_deref() rather than this predicate. [ kkd: Rewrote commit log ] | ||||
| CVE-2026-98039 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Require MEM_PERCPU for percpu kptr stores map_kptr_match_type() treats perm_flags as the set of register type flags that a kptr field permits. Adding MEM_PERCPU to that set for BPF_KPTR_PERCPU does not require the source register to carry it, however. The subset test consequently accepts both a plain bpf_obj_new() allocation and a referenced kernel pointer into a __percpu_kptr map field. Loads from the field are always marked MEM_PERCPU. Consumers then treat the stored value as the cookie returned by bpf_percpu_obj_new(): per-CPU pointer helpers relocate it, and map teardown selects the per-CPU free path. A plain allocation can therefore provide an arbitrary kernel read/write, while a kernel pointer can be relocated into an invalid address or sent through a missing destructor. Require the source MEM_PERCPU flag to match the destination field kind. This preserves valid bpf_percpu_obj_new() stores and rejects both the program-BTF and kernel-BTF variants. | ||||
| CVE-2026-98040 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Mark the zero register precise for a register-form NULL check check_cond_jmp_op() accepts "if rA <op> rB" as a NULL check for a nullable pointer rA when rB is a scalar known to be zero, lifts PTR_MAYBE_NULL from rA in the corresponding branch and does not mark rB precise. Consider the following program: r0 = bpf_get_prandom_u32(); r6 = 1; /* the r6 == 0 path is explored first */ if (r0 == 0) goto 1f; r6 = 0; 1: r0 = bpf_map_lookup_elem(map, &0); /* absent, NULL at runtime */ if (r0 == r6) goto 2f; /* taken as a NULL check for r0 */ *(u8 *)(r0 + 0); /* verifier: map value; runtime: zero */ 2: return 0; The r6 == 0 path is explored first and the dereference is accepted. The r6 == 1 path is pruned at the checkpoint recorded for (1), so the comparison is never verified with a non-zero r6. At runtime a failed lookup returns NULL, NULL != 1 takes the non-NULL edge and the program dereferences a pointer that is zero. | ||||
| CVE-2026-98042 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Don't resurrect a scalar id dropped by collect_linked_regs() check_cond_jmp_op() copies the compared registers into env->{false,true}_reg{1,2} before collect_linked_regs() runs and copies those snapshots back into both branch states afterwards. collect_linked_regs() records at most LINKED_REGS_MAX members of a linked registers group in the jump history and calls clear_scalar_id() for every member that does not fit. The compared register is not exempt from that. As a consequence, sync_linked_regs() might adjust ranges for more registers than bpf_bt_sync_linked_regs() can propagate precision to. Collect the linked registers before the snapshots are taken instead. This might lead to some unnecessary clear_scalar_id's, but from previous testing situations with many linked registers are extremely rare. | ||||
| CVE-2026-98105 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: ethernet: oa_tc6: Improve the error recovery When oversubscribed traffic causes lot of buffer overflow errors, probably due to loss of data chunks, driver fails to find a data chunk with end_valid bit set, before it runs out of sk buffer space. As a result, assert is seen during skb_put. Now, check is made if skb buffer has enough tailroom for the incoming data before accepting. If there is no room, current frame is abandoned and it will start looking for a data chunk with start_valid bit, that is a new frame. SK buffer allocation error is considered as recoverable error. rx_buf_overflow flag is too specific and no longer the only condition this flag is used for. Therefore it is renamed as wait_until_start_valid. This is more appropriate as this flag is used to look for the next data chunk with SV bit set, after failures like buffer overflow, buffer allocation failure, skb pointer validity besides buffer overflow error. Not writing to status0 if it reads 0. | ||||
| CVE-2026-98106 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/pagemap: Prevent double migration of device pages A device-private folio migrated to system memory by a CPU fault can remain reachable through the raw-PFN eviction path until migration finalization drops the source reference. If eviction selects the same device-private folio during this window, it can attempt to migrate the folio again. The second migration can leave an uncharged folio on an LRU list, causing folio_lruvec_lock_irqsave() to retry indefinitely and resulting in a soft lockup and RCU stall. Mark successfully migrated device-private folios using a low bit of their zone_device_data before migration finalization. Make both CPU-fault and raw-PFN migration paths skip device-private folios carrying this flag. Mask the flag when retrieving the drm_pagemap_zdd pointer and preserve it when a device-private folio is split. Keeping the state on the physical folio also avoids depending on a virtual address that may change before a fault occurs. v2: - Replace the retired-PFN XArray with an embedded bitmap. (Matthew Brost) - Mark every base page covered by a migrated folio so retirement remains valid if the folio is later split. v3: - Store the migrated state in a low bit of zone_device_data instead of adding virtual-range and bitmap tracking to the ZDD. (Matthew Brost) - Mask the flag when retrieving the ZDD and preserve it when splitting a folio. - Drop the pre-existing fixes already covered by Matthew Brost's series: https://patchwork.freedesktop.org/series/171651/ v4: - Advance by the folio size only for migration entries marked with MIGRATE_PFN_COMPOUND. (Sashiko) v5: - Simplify ZDD flag updates and folio iteration. (Matthew Brost) - Skip retired device-private folios in the CPU-fault path. (Matthew Brost) - Preserve flag bits while taking a new ZDD reference for split folios. v6: - Restore MIGRATE_PFN_COMPOUND-aware stepping so non-compound migration entries are processed one at a time. (Sashiko) - Drop the pre-existing fixes already covered by Matthew Brost's series: https://patchwork.freedesktop.org/series/171651/ The lockup was observed as: [10109.860465] watchdog: BUG: soft lockup - CPU#9 stuck for 26s!

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: bound firmware ID by TLV length The firmware ID is treated as a NUL-terminated string even though the TLV length is its only boundary. If the value does not contain a NUL terminator, snprintf() can read beyond the received response. Limit the conversion to the advertised TLV value length. | ||||
| CVE-2026-102822 | 1 Eugeny | 1 Russh | 2026-09-29 | 3.7 Low |
| Russh is a Rust SSH client and server library. Prior to 0.63.1, a connection configured to permit mac=none can negotiate it with a MAC-requiring CTR or CBC block cipher because the selection logic validates needs_mac() only when MAC selection fails. A remote peer can then send a packet with a decrypted length of zero, causing russh/src/cipher/mod.rs to shrink the previously read block before indexing buffer.buffer[16..], which panics and terminates the connection task. This issue is fixed in version 0.63.1. | ||||

| CVE-2026-98153 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nvme: fix racy access to FDP placement id array nvme_query_fdp_info() is called per-path and therefore prone to races. It populates head->nr_plids/head->plids for fdp registration. But nothing protects that pair from concurrent access - two paths scanning the same namespace can race to populate it. Avoid the race by moving this initialization work to nvme_alloc_ns_head() which is called once per shared namespace. | ||||
| CVE-2026-102715 | 1 Eclipse | 1 Threadx Netx Duo | 2026-09-29 | N/A |
| Any host on the LAN can send two mDNS records and make the responder write past the end of its transmit packet. The string table stores each name in a slot rounded up to a multiple of four: ```c /* addons/mdns/nxd_mdns.c:11436, 11443, 11447 */ memory_len = ((memory_len & 0xFFFFFFFC) + 8) & 0xFFFFFFFF; ... len = *((USHORT*)(p - 2)); /* slot size, not string length */ if ((len == memory_len) && ... _nx_mdns_name_match(start, memory_ptr, memory_size) ...) ``` The lookup that decides whether an incoming name is already stored compares the rounded slot size, so names of 12, 13, 14 and 15 characters share one bucket. A second name in the bucket is answered with the pointer to the first, and the record then carries a string up to three bytes longer than the length the caller accounted for. `_nx_mdns_packet_rr_add` (nxd_mdns.c:8911) sizes its only bound check from that stale length, and `_nx_mdns_name_string_encode` writes the real string. Two PTR records are enough, both ordinary mDNS responses to a `_http._tcp` query, with owner names whose lengths fall in the same bucket: ``` ==87491==ERROR: AddressSanitizer: heap-buffer-overflow WRITE of size 1 at 0x611000000124 thread T5 #0 _nx_mdns_name_string_encode addons/mdns/nxd_mdns.c:13096 #1 _nx_mdns_packet_rr_add addons/mdns/nxd_mdns.c:8911 0x611000000124 is 0 bytes to the right of 228-byte region ``` The overflow is one to three bytes of attacker-influenced name data past `nx_packet_data_end`. In a normal pool that lands in the next packet in the same pool rather than in a redzone, so the visible effect is a corrupted neighbouring packet or a corrupted pool free list rather than a clean crash. Compare the slot size against the stored string length before declaring a match, or keep the string length in the slot header and return it to the caller so the encoder and the bound check agree. | ||||
| CVE-2026-102242 | 1 Google | 1 Mcp Toolbox For Databases | 2026-09-29 | N/A |
| Improper link resolution (CWE-59 / CWE-22) in the allowedLocalRoots path validation in Google MCP Toolbox for Databases versions 1.2.0 through 1.9.0 allows a remote authenticated attacker with tool execution permissions to bypass directory boundary restrictions via symbolic links. Because path validation checks directories lexically without resolving symbolic links first, an attacker can access or overwrite arbitrary local files located outside the permitted root directories. | ||||
| CVE-2026-88059 | 1 Angular | 1 Angular | 2026-09-29 | 4 Medium |
| Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.28, 21.2.20, and 22.1.1, Angular's @angular/common HttpTransferCache can cache an authenticated response when Server-Side Rendering (SSR) and hydration use a hierarchical HttpClient configured with withRequestsMadeViaParent. The child TransferCache evaluates an initially anonymous request before delegation, then a parent withInterceptors chain adds an Authorization header, cookie, or API token; although the parent cache skips the authenticated request, the child still stores the private response in TransferState serialized as JSON in the ng-state script. Exploitation requires provideClientHydration, child provideHttpClient delegation through withRequestsMadeViaParent, parent-level credential injection, and an SSR HTML response shared across users by a CDN, reverse proxy, or application cache. A later unauthenticated or unauthorized visitor can receive the cached HTML containing the earlier authenticated user's sensitive response data. Applications can mitigate by attaching credentials at the child, filtering sensitive endpoints with withHttpTransferCacheOptions, disabling transfer caching for sensitive routes, or marking personalized HTML private or no-store. This issue is fixed in versions 20.3.28, 21.2.20, and 22.1.1. | ||||

A user induced to connect to an uncontrolled MongoDB deployment using MONGODB-OIDC authentication may have an uncontrolled URI dispatched to their operating system's default protocol handler, potentially exposing credentials or, under certain conditions, resulting in code execution in the user's context. | ||||
| CVE-2026-98118 | 1 Linux | 1 Linux Kernel | 2026-09-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfs: Fix readahead synchronisation issues by loading all folios upfront There are some synchronisation issues that derive from the app thread adding more folios to the rolling buffer whilst the collector thread is looking at them or trying to clear them, such as determining the setting of front_folio_order when the next folio hasn't been added yet, The reason for the rolling buffer approach is that loading the buffer upfront and then dropping all the refs just acquired is quite a slow operation, and loading progressively allows some of the cost to be deferred until after at least some of the I/O is started. Instead, a better way is to load all the folios into the rolling buffer upfront - and then drop the refs later, once the I/O is in progress. (Even better would be for the refs not to be there at all.) Fix this by changing the rolling buffer loader to load all the folios selected by the VM for readahead upfront into the folio queue. The folio queue is allocated a batch worth at a time as we don't know how many folios are involved (the readahead_control struct, alas, has a page count, not a folio count). The folio refs acquired from readahead are then dropped in bulk once the first subrequest is dispatched as it's quite a slow operation. The collector waits for NETFS_RREQ_NEED_PUT_RA_REFS to be cleared so that it doesn't unlock folios before the xarray has been scanned for them. This simplifies the buffer handling later and isn't noticeably slower as the xarray doesn't need to be modified and the folios are all already pre-locked. | ||||
| CVE-2026-19502 | 1 Mongodb | 2 Schema Builder Cli, Sql Schema Builder Cli | 2026-09-29 | 5.5 Medium |
| MongoDB SQL Schema Builder CLI records its startup configuration to standard output and, when file logging is enabled, to a log file on disk. Certain connection settings were written without redaction, so authentication material supplied by the operator could appear in plaintext in that diagnostic output. A local user with read access to the terminal session or the log directory, or anyone with access to a location where those logs are subsequently collected, could obtain those values. | ||||
