Remote web content with required user interaction (UI:R), but the only documented impact is a single web-process crash, so C:N/I:N and A:L rather than the input's full C/I/A:H.

DescriptionCVE.org

The issue was addressed with improved memory handling. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, 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 process crash.

AnalysisAI

Memory-corruption crash in Apple's WebKit web-content engine lets a malicious website terminate the content-rendering process across iOS/iPadOS, macOS, tvOS, visionOS and watchOS prior to the 26.5 (and 18.7.9) releases. The flaw is triggered simply by viewing attacker-controlled web content, requiring no authentication but one user action (opening a page). There is no public exploit identified at time of analysis and SSVC rates exploitation as none, though the assigned CVSS 8.8 reflects worst-case memory-corruption potential rather than the crash-only behavior Apple documents.
