Kernel code execution via unchecked bounds
Published Nov 1, 2022 · Updated May 6, 2025
An out-of-bounds memory access in Apple operating systems before the listed fixes allows local users to execute arbitrary code with kernel privileges via a malicious app. The affected component performs insufficient bounds checking on app-controlled data, enabling memory corruption in kernel context. Exploitation requires installation and execution of a malicious application; successful compromise can affect kernel confidentiality, integrity, and availability.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
