FFmpeg versions 8.0 through 8.1.2 contains a stack buffer overflow vulnerability in the Vulkan HEVC hardware decoder that allows remote attackers to overwrite return addresses and adjacent stack frames by supplying a crafted HEVC/H.265 bitstream. Attackers can embed a malicious vpsnumhrdparameter...

CVE-2026-64831

A flaw was found in FFmpeg. A remote attacker can exploit a stack buffer overflow vulnerability in the Vulkan HEVC High Efficiency Video Coding hardware decoder by providing a specially crafted HEVC/H.265 bitstream. This can lead to overwriting memory on the stack, potentially allowing the attack...
