CVE-2025-69693
Out-of-bounds read in FFmpeg 8.0 and 8.0.1 RV60 video decoder (libavcodec/rv60dec.c).
Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
Description
Out-of-bounds read in FFmpeg 8.0 and 8.0.1 RV60 video decoder (libavcodec/rv60dec.c). The quantization parameter (qp) validation at line 2267 only checks the lower bound (qp < 0) but is missing upper bound validation. The qp value can reach 65 (base value 63 from 6-bit frame header + offset +2 from read_qp_offset) while the rv60_qp_to_idx array has size 64 (valid indices 0-63). This results in out-of-bounds array access at lines 1554 (decode_cbp8), 1655 (decode_cbp16), and 1419/1421 (get_c4x4_set), potentially leading to memory disclosure or crash. A previous fix in commit 61cbcaf93f added validation only for intra frames. This vulnerability affects the released versions 8.0 (released 2025-08-22) and 8.0.1 (released 2025-11-20) and is fixed in git master commit 8abeb879df which will be included in FFmpeg 8.1.
