Last modified

CVE-2026-125095 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. FFmpeg through 9.0.2 contains an uninitialized memory use vulnerability in the C93 video decoder in libavcodec/c93.c, where decode_frame() never checks how many color table bytes were copied. Attackers can supply a crafted truncated Interplay C93 file so draw_n_color() writes uninitialized stack bytes into decoded frames, disclosing stack memory contents.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
