Analysis

Impact

Detailed information about the technical nature and specific impact of the vulnerability is unavailable because the updated description was not provided. The available data indicates the issue involves improper memory handling that could allow an application to read kernel memory, potentially exposing protected data that should not be accessible from user space.

Affected Systems

Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS are affected. The issue is mitigated in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, and watchOS 26.6.

Risk and Exploitability

The CVSS score of 5.5 indicates a moderate impact. The EPSS score of < 1% shows that the likelihood of exploitation is very low, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is through a third‑party application that exploits the memory handling error; this inference is necessary as the exact method is not described.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
