CVE-2026-125069

5.7 MEDIUM 0.2% exploit odds Fix listed Denial of service

What it is

FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in the Motion Pixels decoder because mp_decode_frame() ignores init_get_bits() failure. Attackers supplying a roughly 2^28-byte packet through the libavcodec API overflow the bit count, causing reads from a NULL buffer that crash the process.

Exploit odds: 0.2% chance of exploitation in the next 30 days (EPSS).
Fix: A patch, advisory or fixed version is referenced. Upgrade or apply it.
