Last modified

CVE-2026-125185 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. FFmpeg through 9.0.2 contains a division by zero vulnerability in ff_aom_parse_film_grain_sets() that fails to reject AFGS1 scaling points with repeated x values. Attackers can supply crafted HEVC or VVC files with zero-increment scaling points in T.35 SEI messages, causing generate_scaling() to divide by zero and crash the decoder.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
