CVE-2022-26701Network attack vector

Kernel code execution via IOKit race condition

Published May 26, 2022 · Updated Aug 3, 2024

An IOKit race condition in Apple tvOS before 15.5 allows attackers controlling an application to execute arbitrary code with kernel privileges. Apple identifies improper locking in IOKit but has not disclosed the shared resource, affected function, or sequence of concurrent operations. The application-level entry condition must be met, and successful exploitation crosses the kernel privilege boundary.
