Local denial of service via integer overflow
Published Sep 14, 2026 · Updated Sep 14, 2026
Integer overflow in Apple macOS before 15.8, before 26.7, and before 27 allows local users to cause a denial-of-service through an app. Apple has not identified the affected macOS component or disclosed which integer calculation overflows or how app-controlled input reaches it. Execution of an app on the Mac is required, and the reported consequence is limited to service interruption rather than data access or modification.
