CVE-2024-0519Known exploitationNetwork attack vector

Heap corruption via V8 out-of-bounds access

Published Jan 16, 2024 · Updated Oct 21, 2025

Out-of-bounds memory access in Chrome before 120.0.6099.224 allows remote attackers to corrupt V8 heap memory via crafted HTML. Google has not disclosed the faulty V8 code path or the operation that accesses memory beyond its intended bounds. The victim must load the crafted page; exploitation corrupts browser-process memory, but Google has not specified the resulting post-corruption capability.
