CVE-2022-46699Network attack vector

Code execution via WebKit state mismanagement

Published Dec 15, 2022 · Updated Apr 21, 2025

Memory corruption in Apple WebKit on tvOS before 16.2 and watchOS before 9.2 allows remote attackers to execute code via crafted web content. WebKit mishandles internal state while processing attacker-controlled content, corrupting memory; Apple has not publicly identified the affected routine or memory operation. Execution requires a vulnerable device to process the content and can run code in the WebKit process context.
