DescriptionCVE.org

A use-after-free issue was addressed with improved memory management. This issue is fixed in iOS 26.5 and iPadOS 26.5, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, watchOS 26.5. Processing maliciously crafted web content may lead to an unexpected Safari crash.

AnalysisAI

Safari on Apple platforms crashes when processing maliciously crafted web content due to a use-after-free vulnerability in memory management, resulting in denial of service. Affects iOS and iPadOS below 26.5, macOS Tahoe below 26.5, tvOS below 26.5, visionOS below 26.5, and watchOS below 26.5. Exploitation requires user interaction to visit a malicious webpage but does not allow code execution or information disclosure.

Technical ContextAI

This vulnerability is a use-after-free (CWE-416) memory safety issue in Apple's Safari browser engine. Use-after-free bugs occur when a program references memory that has been previously freed, potentially causing the application to crash or behave unpredictably when attempting to access deallocated memory regions. In this case, the flaw exists in Safari's web content processing pipeline-likely in rendering, JavaScript execution, or DOM manipulation-where improper memory lifecycle management allows freed memory to be accessed. The vulnerability affects Safari's WebKit engine across all major Apple operating systems (iOS, iPadOS, macOS, tvOS, visionOS, watchOS), indicating the flaw is in shared core browser infrastructure. The CVSS vector AV:N/AC:L/PR:N/UI:R indicates the vulnerability requires network delivery of malicious content but needs user interaction (clicking a link, visiting a site).

RemediationAI

Update to the latest security patch immediately: iOS and iPadOS 26.5 or later, macOS Tahoe 26.5 or later, tvOS 26.5 or later, visionOS 26.5 or later, and watchOS 26.5 or later. Patches are available via Settings > General > Software Update on iOS/iPadOS/watchOS devices, System Settings > General > Software Update on macOS, and the corresponding settings on tvOS and visionOS. As a temporary compensating control, restrict users' ability to visit untrusted websites or disable Safari on devices where alternative browsers are available; however, this is operationally restrictive and not recommended long-term. Prioritize patch deployment for shared devices, public kiosks, and high-risk user populations. No configuration changes or feature toggles mitigate this vulnerability-patching is the only effective remedy.
