What is CVE-2026-125237?

FFmpeg versions 8.1 through 9.0.2 contain a denial of service vulnerability due to improper handling of Vulkan hardware acceleration callbacks in the libavcodec library. When processing specially crafted DPX images, functions like start_frame, decode_slice, or end_frame might fail, which leads to an abort during subsequent frames. Attackers can exploit this to terminate the decoding application, affecting its availability and functionality.

Affected Version(s)

FFmpeg 8.1 <= 9.0.2
