CVE-2026-125177
Last modified
CVE-2026-125177 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. FFmpeg through 9.0.2 contains an information disclosure vulnerability in the MSCC/SRGC decoder in libavcodec/mscc.c that outputs uninitialized heap bytes when RLE data ends early. Attackers can craft an MSCC or SRGC stream, such as in AVI, whose RLE data terminates early so the decoded frame exposes leftover heap memory to viewers of the output.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
