CVE-2023-42914

Sandbox escape via undisclosed kernel memory handling

Published Dec 12, 2023 · Updated Nov 4, 2025

Memory-handling flaw in the Apple kernel on affected iOS, iPadOS, macOS, tvOS, and watchOS releases allows local users to escape an app sandbox. Apple identifies the Kernel as the affected component but has not published the faulty memory operation or attacker-controlled input. A malicious app must execute locally; successful exploitation crosses its sandbox boundary, with no reported confidentiality or availability impact.
