Published Sep 26, 2022 · Updated May 22, 2025

Use-after-free in SwiftShader in Google Chrome before 104.0.5112.101 allows remote attackers to corrupt heap memory via crafted HTML. Google has not published the affected function, object lifetime sequence, or invalid access that leaves freed SwiftShader memory reachable. Exploitation requires a user to render the crafted page, and the public record does not establish a consequence beyond heap corruption.
