Linux Distros Unpatched Vulnerability : CVE-2026-62291

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted image sequence with a 2x2 primary plane and a 256x256 auxiliary alp...

CVE-2026-62291

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted image sequence with a 2x2 primary plane and a 256x256 auxiliary alpha plane can cause attacker-controlled heap corruption during a normal decode and re-encode workflow.

CVE-2026-55194 FreeRDPHeap-buffer-overflow write in TS Gateway RPC RESPONSE reassembly due to alloc_hint capacity mismatch

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, rpcclientrecvfragment in libfreerdp/core/gateway/rpcclient.c ensures the response reassembly stream capacity using only the server-declared allochint rather than the actual StubLength about to be written. A maliciou...

EUVD-2026-62580

FFmpeg before commit 1c10bcc contains a heap buffer overflow in the RIST protocol reader libavformat/librist.c. libristread ignored its size argument and copied the full received payload length into the caller-provided destination buffer, overflowing it when the payload exceeds the destination...

CVE-2026-76245

stigmem-node (pip package) version 0.9.0a1 contains a timestamp-handling mismatch in federation peer-token validation that can cause valid peer tokens to be incorrectly treated as expired. This affects the availability and reliability of authenticated federation flows on nodes using federation pe...

CVE-2026-75900 Swtpm: swtpm: out-of-bounds read in swtpm_nvram_checkheader due to sizeof(pointer) vs sizeof(struct) mismatch

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...

Splunk Universal Forwarder 9.4.0 < 9.4.14, 10.0.0 < 10.0.9, 10.2.0 < 10.2.6, 10.4.0 < 10.4.2 (SVD-2026-0803)

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2026-0803 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number...

CVE-2026-18504 fastify vulnerable to schema validation bypass via root primitive coercion mismatch

fastify is a fast and low overhead web framework for Node.js. Versions of fastify before 5.12.1 are affected by a schema validation bypass when a request body schema targets a root primitive value. When the schema validates a top-level primitive such as an integer, Ajv can coerce a JSON string in...

CVE-2026-52829 ZEBRA: IPv4-Mapped Mempool Misbehavior Update Aborts Zebra Address Book

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated IPv4 peer can deterministically terminate a synced Zebra node using the default Linux dual-stack listener configuration. The handshake path canonicalized an IPv4-mapped IPv6 PeerSocketAddr such as ::ffff:127.0.0.1 ...
