CVE-2024-23235

Sensitive-data access via kernel validation race

Published Mar 8, 2024 · Updated Apr 2, 2026

An information disclosure race in affected Apple operating systems allows local apps to access user-sensitive data through the kernel. The kernel inadequately validates shared state during concurrent execution, but Apple has not disclosed the raced resource or affected operation. Exploitation requires an app to execute locally; the reported consequence is limited to unauthorized access to user-sensitive data.
