CVE-2022-22610Network attack vector

Code execution via WebKit state mismanagement

Published Sep 23, 2022 · Updated May 22, 2025

Memory corruption in Apple Safari before 15.4, tvOS before 15.4, and watchOS before 8.5 allows remote attackers to execute code. WebKit mishandles internal state while processing attacker-controlled content and corrupts memory; Apple has not disclosed the affected routine or exact invalid operation. Exploitation requires a user or application to process the content and can run attacker-controlled code in the WebKit process.
