CVE-2024-4058Network attack vector

Heap corruption via ANGLE type confusion

Published May 1, 2024 · Updated Nov 4, 2025

Type confusion in ANGLE in Google Chrome before 124.0.6367.78 allows remote attackers to corrupt heap memory via a crafted HTML page. Public vendor materials identify ANGLE as the affected component but do not disclose the code-level locus or incompatible type operation. The browser must process attacker-controlled HTML, and the capability obtained after heap corruption is not publicly specified.
