CVE-2023-4572Network attack vector

Heap corruption via MediaStream use-after-free

Published Aug 29, 2023 · Updated Feb 13, 2025

Use-after-free in MediaStream in Google Chrome before 116.0.5845.140 allows remote attackers to trigger heap corruption via crafted HTML. Chrome's advisory does not disclose the affected function or the lifetime error that leaves a freed MediaStream object reachable. A remote attacker must convince a user to open the crafted page; successful exploitation corrupts browser heap memory, while the published record does not specify a further outcome.
