CVE-2022-3341 (

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):

Not sure about any backport.
