| CVE-2026-53918 | 2026-10-30 | N/A | N/A | ||
| odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA handler keeps a per-message `first` lease pointer so multiple IA options in one message reuse the same Reconfigure authentication key. A DHCPv6 REQUEST from an adjacent-network client can make the first IA set `first`, then make a later same-IAID IA fail the on-link check and free that same lease, leaving `first` dangling. A following IA in the same packet allocates a new lease and copies `first->key`, producing a 16-byte heap-use-after-free read. ASan confirms the UAF; native tracing shows the packet shape can deterministically reclaim the freed lease as the destination allocation, producing a zeroed Reconfigure key copy. The validated impact is unauthenticated adjacent-network denial of service and DHCPv6 Reconfigure/ForceRenew key confusion. Arbitrary PC control is not proven for this UAF alone. This issue has been patched in version 25.12. | |||||
| CVE-2026-42057 | 2026-10-30 | N/A | 7.5 HIGH | ||
| An invalid pointer dereference vulnerability exists in the vtkPNGReader::vtkPNGReaderUpdate2 functionality of vtk 9.6. A specially crafted .png file can lead to a denial of service. An attacker can provide a malicious file to trigger this vulnerability. | |||||
| CVE-2026-41216 | 2026-10-30 | N/A | 7.5 HIGH | ||

| CVE-2026-102010 | 2026-10-30 | N/A | 7.0 HIGH | ||
| A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption. | |||||
| CVE-2025-49794 | 2026-10-29 | N/A | 9.1 CRITICAL | ||
| A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors. | |||||
| CVE-2026-6747 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-10-26 | N/A | 7.5 HIGH |
| Use-after-free in the WebRTC component. This vulnerability was fixed in Firefox 150, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. | |||||
| CVE-2026-6746 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-10-26 | N/A | 7.5 HIGH |
| Use-after-free in the DOM: Core & HTML component. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. | |||||
| CVE-2026-6100 | 2026-10-26 | N/A | 8.1 HIGH | ||
| Use-after-free (UAF) was possible in the `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile` when a memory allocation fails with a `MemoryError` and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling pointer in this specific error condition. The vulnerability is only present if the program re-uses decompressor instances across multiple decompression calls even after a `MemoryError` is raised during decompression. Using the helper functions to one-shot decompress data such as `lzma.decompress()`, `bz2.decompress()`, `gzip.decompress()`, and `zlib.decompress()` are not affected as a new decompressor instance is used per call. If the decompressor instance is not re-used after an error condition, this usage is similarly not vulnerable. | |||||
| CVE-2026-34001 | 2026-10-26 | N/A | 7.8 HIGH | ||
| A flaw was found in the X.Org X server. This use-after-free vulnerability occurs in the XSYNC fence triggering logic, specifically within the miSyncTriggerFence() function. An attacker with access to the X11 server can exploit this without user interaction, leading to a server crash and potentially enabling memory corruption. This could result in a denial of service or further compromise of the system. | |||||
| CVE-2026-34734 | 1 Hdfgroup | 1 Hdf5 | 2026-10-26 | N/A | 7.8 HIGH |
| HDF5 is software for managing data. In 1.14.1-2 and earlier, a heap-use-after-free was found in the h5dump helper utility. An attacker who can supply a malicious h5 file can trigger a heap use-after-free. The freed object is referenced in a memmove call from H5T__conv_struct. The original object was allocated by H5D__typeinfo_init_phase3 and freed by H5D__typeinfo_term. | |||||
| CVE-2026-35094 | 2 Fedoraproject, Freedesktop | 2 Fedora, Libinput | 2026-10-26 | N/A | 3.3 LOW |
| A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This occurs when a garbage collection cleanup function is called, leaving a pointer that can then be printed to system logs. This could potentially expose sensitive data if the memory location is re-used, leading to information disclosure. For this exploit to work, Lua plugins must be enabled in libinput and loaded by the compositor. | |||||
| CVE-2026-8090 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-10-26 | N/A | 7.3 HIGH |
| Use-after-free in the DOM: Networking component. This vulnerability was fixed in Firefox 150.0.2, Firefox ESR 140.10.2, Firefox ESR 115.35.2, Thunderbird 150.0.2, and Thunderbird 140.10.2. | |||||
| CVE-2026-7111 | 1 Hmbrand | 1 Text\ | 2026-10-26 | N/A | 8.4 HIGH |
| Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption. The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead. Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected. | |||||

| CVE-2026-12328 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-10-26 | N/A | 8.1 HIGH |
| Memory safety bugs present in Firefox ESR 115.36, Firefox ESR 140.11, Thunderbird ESR 140.11, Firefox 151 and Thunderbird 151.

| CVE-2026-57435 | 1 Nokogiri | 1 Nokogiri | 2026-10-25 | N/A | 7.5 HIGH |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri’s CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, Nokogiri::XML::Attr#value= could free the underlying native child node while the wrapper remained reachable through the document node cache. A later use of the freed child node or a Ruby GC mark could dereference an invalid pointer, causing an invalid read and a possible segfault. This vulnerability is fixed in 1.19.4. | |||||
