libav before 12.1 is vulnerable to an invalid read of size 1 due to NULL pointer dereferencing in the nsv_read_chunk function in libavformat/nsvdec.c.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
