CVE-2022-32863Network attack vector

Arbitrary code execution via WebKit state mishandling

Published Sep 20, 2022 · Updated Aug 3, 2024

Memory corruption in WebKit in Apple macOS before 12.5 allows remote attackers to execute arbitrary code via malicious web content. WebKit mishandles state while processing attacker-controlled web content, corrupting memory; Apple has not published the affected function or operation. Successful exploitation requires the target to process crafted web content and yields code execution in the WebKit process, without a documented sandbox escape or privilege gain.
