Kernel memory disclosure or crash via out-of-bounds read
Published Apr 2, 2021 · Updated Aug 4, 2024
Out-of-bounds read in the macOS Sandbox allows local users to crash the system or read kernel memory through malformed input. The Sandbox component insufficiently validates attacker-controlled input before reading beyond a buffer boundary; Apple has not disclosed the affected routine or input format. A local low-privileged account is required, and successful exploitation exposes kernel memory or terminates the entire host.

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.
