This issue was addressed with improved authentication. This issue is fixed in iOS 18.7.7 and iPadOS 18.7.7, iOS 26.4 and iPadOS 26.4, macOS Sequoia 15.7.5, macOS Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4. An app may be able to leak sensitive kernel state.
AnalysisAI
A kernel state information disclosure vulnerability exists across Apple's entire platform ecosystem that allows a malicious application to leak sensitive kernel memory without requiring elevated privileges. The vulnerability affects iOS and iPadOS versions prior to 18.7.7 and 26.4, macOS Sequoia prior to 15.7.5, macOS Tahoe 26.4, and tvOS, visionOS, and watchOS 26.4. An attacker can craft a specially designed app that exploits improper authentication mechanisms to access protected kernel state, potentially exposing cryptographic keys, memory addresses, or other sensitive operating system internals that could be chained with other vulnerabilities.
Technical ContextAI
This vulnerability is classified as an Information Disclosure issue (CWE not explicitly provided but implied to be related to improper authentication and access control in kernel-level operations). The affected technologies span Apple's entire platform architecture including iOS/iPadOS (cpe:2.3:a:apple:ios_and_ipados), macOS (cpe:2.3:a:apple:macos), tvOS (cpe:2.3:a:apple:tvos), visionOS (cpe:2.3:a:apple:visionos), and watchOS (cpe:2.3:a:apple:watchos). The root cause appears to involve insufficient authentication validation when user-space applications attempt to access kernel state or memory regions that should be restricted. Rather than enforcing proper permission boundaries, the kernel failed to properly authenticate requests from third-party applications, allowing arbitrary apps to read sensitive kernel data structures.
RemediationAI
Update all Apple devices to the patched versions immediately: iOS and iPadOS to version 18.7.7 or 26.4 or later, macOS Sequoia to version 15.7.5 or later, macOS Tahoe to 26.4 or later, tvOS to 26.4 or later, visionOS to 26.4 or later, and watchOS to 26.4 or later. Consult the specific support articles (https://support.apple.com/en-us/126792-126799) for your device platform to confirm the exact update path. For organizations unable to immediately deploy patches, enforce strict app vetting policies through Mobile Device Management (MDM) to prevent installation of untrusted applications, and monitor for suspicious app behavior. Consider restricting installation of third-party applications from untrusted developers until patches can be deployed, as the vulnerability requires local app execution to exploit.
