Subject: [FFmpeg-devel] [PATCH] avcodec/rv60dec: add upper bound check for qp
Date: Fri, 7 Nov 2025 18:20:38 +0100
Message-ID: <CAJ9qJsucu9XiGkPmqDz6Os6FKBz7Yg93RAVu9pgVpYRrVbpVNw@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 242 bytes --]

This patch fixes an out-of-bounds read in the RV60 decoder where qp can
reach 65, exceeding the rv60_qp_to_idx[64] array bounds. The previous fix
(61cbcaf93f) only covered intra frames. This adds validation at the source
for all frame types.
