Out-of-bounds memory access via uninitialized media data
Published Aug 3, 2021 · Updated Aug 3, 2024
Uninitialized use in Google Chrome Media before 92.0.4515.107 allows remote attackers to access out-of-bounds memory via crafted HTML. The public vendor and CNA records identify the Media component but do not disclose the affected function or how uninitialized data reaches an out-of-bounds access. Exploitation requires a user to open attacker-controlled HTML; the published record supports memory access but does not establish code execution or a browser-sandbox escape.
