CVE-2022-3450Network attack vector

Heap corruption via Peer Connection use-after-free

Published Nov 9, 2022 · Updated Oct 23, 2024

Use-after-free in Google Chrome's Peer Connection before 106.0.5249.119 allows remote attackers to corrupt heap memory via crafted HTML. Public vendor material identifies the Peer Connection component but does not disclose the freed object, function, or lifetime error that leaves a stale reference. Exploitation requires a user to load attacker-controlled HTML; successful heap corruption can compromise browser confidentiality, integrity, and availability.
