CVE-2023-0930Network attack vector

Heap corruption via crafted video content

Published Feb 22, 2023 · Updated Feb 13, 2025

Heap buffer overflow in Google Chrome's Video component before 110.0.5481.177 allows remote attackers to corrupt heap memory via crafted HTML. The public Chrome advisory identifies the Video component and crafted HTML trigger but does not disclose the faulty buffer operation or affected codec path. A user must load attacker-controlled content; the record confirms heap corruption but does not establish whether exploitation stops at a crash or permits code execution.
