CVE-2024-5159Network attack vector

Out-of-bounds read via ANGLE heap overflow

Published May 22, 2024 · Updated Feb 13, 2025

Heap buffer overflow in ANGLE in Google Chrome before 125.0.6422.76 allows remote attackers to read out-of-bounds memory via crafted HTML. Google has not published the affected ANGLE function or the malformed-input operation that crosses the heap-buffer boundary. A user must open the crafted page, and the source record documents an out-of-bounds memory read rather than direct code execution.
