Alert meAnalysisAIv1 – Sep 15, 2026
A type confusion flaw (CWE-843) in memory handling across Apple's current operating system family lets a malicious app crash the affected device or component, producing a local denial of service. Exploitation requires the victim to install and launch a crafted app — the CVSS vector is AV:L/PR:N/UI:R with availability-only impact, so there is no remote unauthenticated path and no confidentiality or integrity loss. Apple has shipped fixes in iOS/iPadOS 26.7 and 27, macOS Sequoia 15.8, macOS Tahoe 26.7 and macOS Golden Gate 27, plus tvOS 27, visionOS 27 and watchOS 27; EPSS is only 0.17% (6th percentile) and there is no public exploit identified at time of analysis, so this is a routine patch-cycle item rather than an urgent exposure.

Attack Technique
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.
