Published Jul 28, 2022 · Updated Aug 3, 2024

Use-after-free in Guest View in Google Chrome before 103.0.5060.134 allows attackers to exploit heap corruption via crafted HTML. Google has not published the affected Guest View object or the operation that accesses it after its lifetime ends. Exploitation requires a user to install a malicious extension; public records establish heap corruption but no more specific downstream outcome.
