Trigger is a physically connected malicious accessory (AV:P over vendor's AV:L) with victim action (UI:R); impact is availability-only (A:H, C:N/I:N) as the flaw only causes system termination.

DescriptionCVE.org

A memory corruption issue was addressed with improved input validation. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Tahoe 26.7. Connecting a malicious accessory may cause unexpected system termination.

AnalysisAI

Connecting an attacker-controlled hardware accessory to an unpatched iPhone, iPad, or Mac can drive a memory corruption fault that terminates the system (unexpected system termination) in iOS/iPadOS before 26.7 and before 27, and in macOS Tahoe before 26.7 and macOS Golden Gate before 27. The vendor describes the root cause as insufficient input validation (CWE-20) on data supplied by the attached peripheral; the vector requires no privileges on the target device (PR:N) but does require the victim to physically attach the malicious accessory and to interact with it (UI:R), and the impact is availability-only with no confidentiality or integrity loss. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an attacker-controlled physical accessory (peripheral/hardware) to be connected to the target Apple device, and the description explicitly frames the trigger as 'connecting a malicious accessory.' Limiting factors are significant: the attacker must supply malicious hardware and rely on the victim physically attaching it (UI:R), the vector is local/physical rather than network-reachable, privileges are not required on the device itself, and the outcome is limited to a crash (system termination) with no persistence, code execution, or data access. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a low-to-moderate priority availability-only 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 Apply the vendor fixes: update to iOS 26.7 or iPadOS 26.7 (or the iOS 27 / iPadOS 27 branch) and to macOS Tahoe 26.7 or macOS Golden Gate 27, as documented in Apple advisories https://support.apple.com/en-us/149034, https://support.apple.com/en-us/149035, https://support.apple.com/en-us/149041, and https://support.apple.com/en-us/149042; patch status is Vendor-released patch with those exact versions. … Detailed patch versions, workarounds, and compensating controls in full report.
