Denial of service via unexpected app termination affects multiple Apple operating systems, including iOS, iPadOS, macOS, tvOS, watchOS, and visionOS, when processing a malicious accessory. The vulnerability stems from a buffer overflow (CWE-120) addressed with improved bounds checking in the latest updates. No active exploitation or public proof-of-concept is reported; EPSS score is low (0.18%), though the provided CVSS vector implies a critical network-based attack that does not align with the accessory requirement.
