CVE-2026-58049

FFmpeg's RASC video decoder decodedlta in libavcodec/rasc.c performs 32-bit reads and writes at the row cursor before the NEXTLINE row-boundary check and validates the DLTA region in pixel rather than byte units, so a DLTA run on a PAL8 frame can access several bytes past the row allocation. A...

CVE-2026-58049

CVE-2026-58049 concerns FFmpeg’s RASC video decoder (decode_dlta in libavcodec/rasc.c). The issue arises when the code performs 32-bit reads/writes at the row cursor before the NEXT_LINE boundary check and validates the DLTA region in pixels rather than bytes. On PAL8 frames, this enables a DLTA ...
