CVE-2026-45383

A flaw was found in libde265, an open-source implementation of the H.265 video codec. A remote attacker could exploit a heap buffer overflow vulnerability by providing specially crafted video files. This occurs when decoding a Wavefront Parallel Processing WPP HEVC slice, where malformed headers...
