CVE-2024-23208

Kernel code execution via improper memory handling

Published Jan 23, 2024 · Updated Apr 2, 2026

Memory corruption in the Apple Kernel allows local users to execute arbitrary code with kernel privileges across four operating-system families. Apple states that improved memory handling resolves the issue but has not disclosed the faulty memory operation or attacker-controlled input. Affected releases are iOS and iPadOS before 17.3, macOS before 14.3, tvOS before 17.3, and watchOS before 10.3; execution of an app is required.
