CVE-2024-12381Network attack vector

Heap corruption via V8 type confusion

Published Dec 11, 2024 · Updated Dec 17, 2024

Type confusion in V8 in Google Chrome before 131.0.6778.139 allows remote attackers to corrupt heap memory via crafted HTML. Rendering attacker-controlled HTML triggers incompatible-type access; Google has not disclosed the affected V8 code path or types. Exploitation requires a user to load the crafted page, and the public record establishes heap corruption but not a specific post-corruption outcome.
