CVE-2024-12693Network attack vector

Sandboxed code execution via V8 out-of-bounds access

Published Dec 18, 2024 · Updated Mar 13, 2025

Out-of-bounds memory access in Google Chrome before 131.0.6778.204 allows remote attackers to execute code inside V8's sandbox via crafted HTML. Google identifies the locus only as V8 and has not disclosed which operation accesses memory beyond its intended bounds; the linked bug remains restricted. A user must load attacker-controlled HTML, and successful exploitation remains confined to the browser sandbox absent a separate escape.
