CVE-2026-68206

A flaw was found in the Linux kernel's V4L2 controls for High Efficiency Video Coding HEVC. The common validation path for HEVC slice parameters does not properly verify the active L0/L1 reference counts before driver-specific code processes them. This lack of validation could allow a local user ...

CVE-2026-68206 media: v4l2-ctrls: validate HEVC active reference counts

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC active reference counts HEVC slice parameters are shared stateless V4L2 controls, but the common validation path does not verify the active L0/L1 reference counts before driver-specific code...

CVE-2026-68206

The CVE concerns the Linux kernel media stack (v4l2-ctrls) where HEVC slice parameters are exposed as stateless V4L2 controls. Root cause: the common HEVC slice control validation did not verify the active L0/L1 reference counts before driver-specific code consumed them, potentially allowing out-...

USN-8573-1: libde265 vulnerabilities

It was discovered that libde265 did not properly manage memory under certain circumstances. An attacker could possibly use this issue to cause libde265 to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS. CVE-2023-51792 It was discovered that libde265 did not...

CVE-2026-49337

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes decodercontext::readsliceNAL libde265/decctx.cc:481 to attach slice headers to a finished picture object that has no active image unit, resulting in...

CVE-2026-53702

A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library gst-plugins-bad. When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpbcntminus1i the loop index instead of the sub-layer 0 CPB count cpbcntminus10 from the referenced...
