Heap corruption via Performance Manager use-after-free
Published Oct 8, 2021 · Updated Aug 4, 2024
Use-after-free in Performance Manager in Google Chrome before 94.0.4606.54 allows remote attackers to trigger heap corruption via crafted HTML. The Performance Manager operates on an object whose lifetime has ended, enabling heap corruption when processing crafted page data in a compromised renderer. Exploitation requires a renderer process already compromised by the attacker; the documented consequence is potential memory corruption, with no separate evidence of data disclosure or service interruption.
