CVE-2022-4192Network attack vector

Heap corruption via Live Caption use-after-free

Published Nov 29, 2022 · Updated Aug 3, 2024

Use-after-free in Live Caption in Google Chrome before 108.0.5359.71 allows remote attackers to corrupt heap memory through UI interaction. Public records identify Live Caption as the affected component but do not disclose which object is freed prematurely or how later UI processing reuses its stale reference. Exploitation requires convincing a user to perform specific UI interaction; the published record establishes heap corruption but documents no narrower operational consequence.
