CVE-2022-3341 (https://bugzilla.redhat.com/show_bug.cgi?id=2157054):

A null pointer dereference issue was discovered in 'FFmpeg' in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash.

Patch (in 5.1): https://github.com/FFmpeg/FFmpeg/commit/9cf652cef49d74afe3d454f27d49eb1a1394951e

Not sure about any backport.
