Description

FFmpeg through 9.0.2 contains a heap out-of-bounds read vulnerability in v4l2_buffer_swframe_to_buf() in libavcodec/v4l2_buffers.c that mishandles frames with negative linesize. Attackers can supply bottom-up AVI or PNM/PFM files that are transcoded to a V4L2 M2M encoder, crashing the application or leaking heap memory into encoded output.
