High [CVE-2026-64831] Arbitrary code execution via crafted HEVC/H.265 bitstream
CVE-2026-64831Source published Source updated
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 vps_num_hrd_parameters value exceeding HEVC_MAX_SUB_LAYERS in any supported container format to overflow stack-allocated arrays in the vk_hevc_end_frame function, potentially achieving arbitrary code execution. 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 attacker to…
