Kernel code execution via unchecked graphics-driver input
Published May 26, 2022 · Updated May 30, 2025
An out-of-bounds read in Apple's Intel Graphics Driver allows local users on affected macOS releases to execute code with kernel privileges. The driver processes application-controlled input without sufficient bounds validation, permitting a read beyond the intended buffer; Apple has not disclosed the affected routine or input structure. Execution requires a malicious local application and user interaction on an affected Catalina, Big Sur, or Monterey system, and successful exploitation grants kernel-level code execution.

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.
