Kernel-address disclosure via unredacted log entries
Published Jul 29, 2024 · Updated Apr 2, 2026
Information disclosure in the kernel of affected Apple operating systems allows local users to determine kernel memory layout. Kernel logging fails to redact private address data from log entries, exposing layout information that should remain hidden. The attacker requires low-privilege local execution, and the disclosed layout weakens address-randomization defenses without directly modifying data or interrupting service.

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.
