CVE-2022-46696Network attack vector

Arbitrary code execution via WebKit memory corruption

Published Dec 15, 2022 · Updated Apr 21, 2025

Memory corruption in WebKit in Apple tvOS before 16.2 and watchOS before 9.2 allows remote attackers to execute code via malicious web content. Apple identifies inadequate input validation but has not published the affected WebKit function, input field, or exact corrupting operation. Exploitation requires processing attacker-controlled web content and user interaction, and successful exploitation runs arbitrary code in the affected WebKit process.
