The issue was addressed with improved memory handling. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An app may be able to cause unexpected system termination.
AnalysisAI
Improper memory handling in Apple iOS, iPadOS, and macOS lets a locally running application trigger an unexpected system termination, crashing the device or the operating system; affected versions are iOS/iPadOS prior to 26.7 or 27, and macOS prior to Golden Gate 27, Sequoia 15.8, and Tahoe 26.7. The only prerequisite is the ability to run a malicious or malformed app on the target device (local access, PR:L, no user interaction and no network reachability), and the demonstrated impact is limited to availability - no code execution, privilege escalation, or data access. …

Vulnerability AssessmentAI
| Exploitation | Requires the ability to run a malicious or malformed application on the target device (local access, PR:L per the CVSS vector) across default configurations of iOS/iPadOS or macOS; no user interaction beyond running the app and no network access is involved. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-priority issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, and macOS Tahoe 26.7; apply these updates via standard Apple software update or MDM-pushed OS updates, using the advisories at https://support.apple.com/en-us/149034, https://support.apple.com/en-us/149035, https://support.apple.com/en-us/149041, https://support.apple.com/en-us/149042, and https://support.apple.com/en-us/149043 to map each platform to its fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
