A validation issue was addressed with improved input sanitization. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. A maliciously crafted app may be able to bypass code signing enforcement.
Executive ViewAI
A code signing bypass vulnerability in Apple operating systems allows a malicious app to execute with high confidentiality and integrity impact, potentially leading to data breaches or system compromise. This affects all Apple device users across the enterprise, including macOS, iOS, and iPadOS. Leadership should prioritize patching to prevent unauthorized code execution and maintain trust in the platform's security.
Within 24 hours, identify all Apple devices (macOS, iOS, iPadOS) running versions prior to 26.6 and begin planning an emergency patch deployment. Over the next 7 days, test the vendor-released patch (version 26.6) in a controlled environment and deploy to all managed devices. Within 30 days, verify full patch coverage and ensure no unpatched systems remain, while monitoring for any signs of exploitation attempts leveraging this vulnerability.
Apply vendor patch.
