| CVE-2026-93424 | 1 Pavel-odintsov | 1 Fastnetmon | 2026-11-05 | 7.5 High |
| FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, peer_find_template() in src/netflow_plugin/netflow_collector.cpp and src/netflow_plugin/netflow_v9_collector.cpp returns a pointer into global_netflow9_templates after releasing the cache mutex. On deployments with at least two entries in netflow_ports, concurrent template redefinition and data-flowset processing can let add_update_peer_template() reassign the template and free its records vector while another listener dereferences the escaped pointer. An unauthenticated sender that can reach both NetFlow/IPFIX listener ports can trigger a heap-use-after-free and reliably crash FastNetMon. No fixed release is available as of this review. | ||||
| CVE-2026-65586 | 1 Imaginationtech | 1 Graphics Ddk | 2026-11-05 | 7.1 High |
| Software installed and run as a non-privileged user may conduct improper GPU system calls to free memory in still in use, replace with another allocation and cause arbitrary memory reads or writes to physical memory pages. A memory buffer managed by a CPU thread of control (driver) and accessed by a GPU thread of control (firmware) can be freed while in use. Software installed and run as a non-privileged user may replace that buffer with another and replace a shared resource (memory page address list) managed by the CPU thread of control (driver) leading to the GPU accessing memory not managed by the CPU thread of control (driver). | ||||
| CVE-2026-15466 | 1 Imaginationtech | 1 Graphics Ddk | 2026-11-05 | 7.0 High |
| Software installed and run as a non-privileged user may conduct improper GPU system calls to cause race condition in hardware performance counters buffer’s destruction path leading to read and/or write UAF. The race condition in the destruction path could lead to reference counter being decremented in non-atomical way allowing other code paths using a freed object to read and/or write kernel heap memory. | ||||
| CVE-2026-58381 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhel Els | 2026-11-05 | 6.1 Medium |
| A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the read_layer_block() function when processing a specially crafted PSP file. This could allow an attacker to cause memory corruption, potentially leading to denial of service or arbitrary code execution. | ||||
| CVE-2026-55653 | 3 Openbsd, Openssh, Redhat | 13 Openssh, Openssh, Enterprise Linux and 10 more | 2026-11-05 | 4.3 Medium |
| A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). | ||||
| CVE-2026-112531 | 1 Apple | 1 Macos | 2026-11-05 | 7.5 High |
| A use after free issue was addressed with improved memory management. This issue is fixed in macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2. An app may be able to cause unexpected system termination. | ||||
| CVE-2026-50263 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-11-05 | 5.5 Medium |
| A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure. | ||||
| CVE-2026-58857 | 1 Google | 1 Android | 2026-11-05 | 8.1 High |
| In decrypt of CryptoHalHidl.cpp, there is a possible use-after-free due to a race condition. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. | ||||
| CVE-2026-4271 | 2 Gnome, Redhat | 4 Libsoup, Enterprise Linux, Enterprise Linux Eus and 1 more | 2026-11-05 | 5.3 Medium |
| A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Use-After-Free, occurs in the HTTP/2 server implementation. A remote attacker can exploit this by sending specially crafted HTTP/2 requests that cause authentication failures. This can lead to the application attempting to access memory that has already been freed, potentially causing application instability or crashes, resulting in a Denial of Service (DoS). | ||||
| CVE-2026-117975 | 1 Mozilla | 1 Firefox | 2026-11-05 | 8.8 High |
| Sandbox escape due to invalid pointer in the Graphics: WebRender component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6. | ||||
| CVE-2026-19548 | 2 Gnu, Redhat | 8 Binutils, Adminutil, Enterprise Linux and 5 more | 2026-11-05 | 5.5 Medium |
| Multiple Use-After-Free vulnerabilities were found in the add_archive_element function in ld/ldmain.c of the GNU linker (ld), a component of binutils. The root cause is that plugin_maybe_claim() in ld/plugin.c frees the original BFD object via bfd_close/_bfd_delete_bfd when entry->the_bfd->my_archive == NULL, but the caller retains both the original abfd parameter and a shallow copy (orig_input.the_bfd) as dangling pointers. These dangling pointers are subsequently dereferenced at three distinct locations in add_archive_element: 1. Line ~1442: accessing abfd->my_archive via bfd_usrdata(abfd->my_archive) 2. Line ~1493: multiple accesses to abfd and abfd->my_archive in a conditional check and bfd_get_filename call 3. Line ~1525: dereferencing the shallow copy orig_input.the_bfd->my_archive in trace/verbose logging The vulnerability is triggered when LTO plugins are active (link_info.lto_plugin_active is true) and the input object has abfd->my_archive == NULL, which is a valid state for standalone object files. Red Hat builds binutils with --enable-plugins and --enable-lto, confirming the vulnerable code path is compiled in and reachable. An attacker who can supply a crafted object or archive file to a build process using LTO-enabled linking could exploit this flaw to cause a denial of service (linker crash via segmentation fault). Arbitrary code execution is theoretically possible through heap manipulation but is substantially mitigated by hardening measures including stack protector, FORTIFY_SOURCE, ASLR, and PIE. The attack surface is limited to build-time environments — the linker is a development tool not exposed in production runtime. The most realistic exploitation scenario is a supply chain attack introducing a crafted object file as a build dependency in CI/CD pipelines or development environments. | ||||
| CVE-2026-18663 | 1 Redhat | 3 Directory Server, Enterprise Linux, Rhel Els | 2026-11-05 | 5.9 Medium |
| A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function frees the parsed controls array on the Session Tracking critical-control rejection path without clearing the SLAPI_REQCONTROLS pblock slot. Operation teardown then frees the same pointer again, causing a double-free. An unauthenticated remote attacker can trigger this with a single BIND request carrying a critical Session Tracking control, resulting in heap corruption and potential denial of service. | ||||
| CVE-2026-121963 | 1 Freerdp | 1 Freerdp | 2026-11-05 | 5.9 Medium |
| FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel that allows malicious RDP servers to trigger freed callback access by closing the channel with queued audio PDUs. Attackers can send a training PDU then close the channel so the playback thread reads the freed callback in rdpsnd_virtual_channel_write, crashing the client. | ||||
| CVE-2026-117982 | 1 Mozilla | 1 Firefox | 2026-11-05 | 9.8 Critical |
| Invalid pointer in the JavaScript Engine: JIT component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6. | ||||
