Executive Summary

This vulnerability is an out-of-bounds read issue in the Vp9DecEndOfStream function of vp9hwd_output.cc.

Impact Analysis

This vulnerability could allow an attacker to read sensitive memory data, potentially leading to unauthorized access or privilege escalation on the affected system. Since no user interaction is required, it may be exploited silently.
