CVE-2024-23264

Restricted-memory disclosure via unsanitized Metal input

Published Mar 8, 2024 · Updated Apr 2, 2026

Out-of-bounds read in Metal in affected Apple operating systems allows local users to read restricted memory via crafted application input. Metal inadequately validates and sanitizes application-supplied input before accessing memory, but Apple has not disclosed the affected API or data structure. Execution of an application on the device is required, and the documented consequence is confined to unauthorized memory disclosure.
