Doc Text:
A flaw was found in FFmpeg. An attacker can cause a Denial of Service (DoS) by providing a specially crafted, oversized packet to the Motion Pixels decoder. Because the decoder fails to detect an initialization error when processing the stream, the application attempts to read from an unallocated memory address, resulting in a process crash.

Description OSIDB Bzimport 2026-11-10 19:51:25 UTC 
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.
