Processing maliciously crafted web content may lead to an unexpected process crash.

AnalysisAI

Apple's iOS, iPadOS, macOS, tvOS, visionOS, and watchOS contain a use-after-free vulnerability that could allow remote attackers to crash affected applications by processing maliciously crafted web content. The vulnerability stems from improper memory management and requires user interaction to exploit. No patch is currently available, leaving users vulnerable until official updates are released.

Technical ContextAI

This vulnerability is a use-after-free memory safety issue within WebKit, Apple's rendering engine responsible for processing web content across all affected platforms (iOS, iPadOS, macOS, tvOS, visionOS, watchOS). Use-after-free vulnerabilities (related to CWE-416) occur when code attempts to access memory that has already been freed, resulting in undefined behavior. The affected products span multiple CPU architectures and operating systems: iOS and iPadOS (cpe:2.3:a:apple:ios_and_ipados:*:*:*:*:*:*:*:*), macOS variants including Sequoia, Sonoma, and Tahoe (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 vulnerability is triggered during the processing of web content, suggesting the attack vector is network-based and requires no authentication.

RemediationAI

Immediately update to the patched versions: iOS/iPadOS 18.7.7 or 26.4, macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4, tvOS 26.4, visionOS 26.4, and watchOS 26.4. Consult Apple's security bulletins at https://support.apple.com/en-us/126792 through https://support.apple.com/en-us/126799 for platform-specific patch instructions. As a temporary mitigation, restrict web browsing to trusted sites only and disable JavaScript if the user can tolerate reduced functionality, though neither measure fully eliminates risk. For enterprise deployments, enforce Mobile Device Management (MDM) policies to mandate updates and consider deploying content filtering to restrict access to potentially malicious web sources until all endpoints are patched.
