Heap corruption via V8 TurboFan type confusion
Published Jul 26, 2022 · Updated Oct 21, 2025
Type confusion in V8 TurboFan in Google Chrome before 100.0.4896.127 allows remote attackers to trigger heap corruption via crafted HTML. Google has not published the specific TurboFan optimization or incorrect type operation that produces the corrupted heap state. Exploitation requires a user to load attacker-controlled HTML in the browser; Google and CISA report active exploitation, but neither source specifies the final payload.
