CVE-2024-12695Network attack vector

Sandboxed code execution via V8 out-of-bounds write

Published Dec 18, 2024 · Updated Jan 6, 2025

Out-of-bounds write in Google Chrome's V8 before 131.0.6778.204 allows remote attackers to execute code inside the sandbox via crafted HTML. A crafted page causes V8 to write beyond the intended memory buffer; Google has not disclosed the affected function or faulty bounds operation. The attacker needs no privileges, but a user must open the page, and the reported execution remains confined to Chrome's sandbox.
