Description OSIDB Bzimport 2026-11-10 20:28:46 UTC 
FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in libavcodec/dpx.c that leaves dpx->hwaccel_picture_private allocated when Vulkan hwaccel callbacks fail. Attackers can supply crafted DPX images that make start_frame, decode_slice or end_frame fail, triggering an av_assert0 abort on the next frame and terminating the decoding application.
