Description Avinash Hanwate 2026-09-17 15:19:39 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A NULL pointer dereference in the get_min_buffer_size function (/libswscale/slice.c) of FFmpeg N-122528-gdd2976b9e1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted video file.
