A race condition exists in Apple operating system state handling that can be triggered by an application, leading to unexpected system termination. The flaw is catalogued as CWE-362. The vulnerability does not provide privilege escalation or data exposure; its impact is limited to denial of service.

Apple iOS, iPadOS, macOS Tahoe, tvOS, and watchOS running any version before iOS 26.6, iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6, or watchOS 26.6 are affected. The entry does not list specific older releases.

The CVSS base score of 9.8 indicates severe impact. The EPSS score of less than 1% and absence from the CISA KEV catalog suggest low current exploitation likelihood. Exploitation would require an application to trigger the race condition; the description does not specify the privilege level required, so the likely attack vector is local or application‑level, which is inferred from the mention of an app. The absence of detailed exploitation steps or required timing makes the likelihood of a successful attack uncertain.
