Alert meAnalysisAIv1 – Sep 15, 2026
A use-after-free (CWE-416) in Apple's memory management code allows a locally running application on iOS, iPadOS, macOS, tvOS, visionOS and watchOS to crash the affected system, producing an unexpected termination or reboot. The flaw affects all platforms before the fixed releases (iOS/iPadOS 26.7 and 27, macOS Sequoia 15.8, macOS Tahoe 26.7, macOS Golden Gate 27, tvOS 27, visionOS 27, watchOS 27) and rates CVSS 5.5 (AV:L/PR:L/UI:N, availability-only impact). No public exploit code or active exploitation has been identified, and EPSS is low at 0.21% (11th percentile), so this is a patched, availability-only issue rather than an urgent remote-code-execution threat.

Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
