CVE-2026-125248

FFmpeg 9.0 through 9.0.2 contains an integer overflow vulnerability in libavcodec/ffv1enc_vulkan.c that undersizes the float remap GPU buffer for large frames. Attackers can supply large GBRPF32 or GBRAPF32 images or videos that, when transcoded to FFV1 with the Vulkan encoder, trigger out-of-bounds GPU memory writes causing crashes or memory corruption.
