Executive Summary

This vulnerability is an out-of-bounds read occurring in the read_global_param() function within the av1dec.c file of FFmpeg version 8.0.1. An out-of-bounds read means the program reads data outside the intended memory boundaries, which can lead to unexpected behavior.

Specifically, this flaw allows attackers to craft a malicious input that triggers this improper memory access.

The consequence of this vulnerability is a Denial of Service (DoS), meaning the affected software can crash or become unresponsive when processing the crafted input.
