The vulnerability allows a maliciously crafted image to corrupt process memory within Apple operating systems. The advisory notes that this corruption can occur but does not confirm it can be leveraged for code execution or broader compromise. The weakness is classified as buffer overflow (CWE-119).

Apple devices running iOS and iPadOS versions 26.5 or earlier, macOS Sequoia 15.7.7 or earlier, macOS Sonoma 14.8.7 or earlier, macOS Tahoe 26.5 or earlier, tvOS 26.5 or earlier, visionOS 26.5 or earlier, and watchOS 26.5 or earlier are affected.

The CVSS score is 7.5, and the EPSS score is < 1%; these metrics indicate a moderate to high severity with a very low but nonzero probability of exploitation. It is inferred that the flaw can be triggered purely by characteristics of the image data and does not require system compromise or elevated privileges to trigger the memory corruption. It is inferred that attackers could deliver a malicious image through any medium that the device’s image‑handling subsystem parses, such as email attachments, web content, or local files.
