Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability is a Use-After-Free in WebCore::Style::TreeResolver::styleForElement, triggered via crafted web content manipulating DOM elements (appendChild, scrollIntoView) across event handlers
  • ASan memory pattern shows freed heap region (0xfd bytes) being accessed — heap UAF crash signature useful for crash triage/fuzzing harness validation
  • PoC exploit uses DOM manipulation via appendChild() and scrollIntoView() across multiple event handlers to trigger the UAF condition in WebKit's style resolver
  • Crash process PID 30588 aborted by ASan — monitor for WebKit/Safari/WebContent process crashes with ABORTING signal as potential exploitation indicator
  • ·Vulnerability affects multiple Apple products; patched versions are iOS 11.1, Safari 11.0.1, iCloud for Windows 7.1, iTunes 12.7.1 for Windows, and tvOS 11.1 — detection should target unpatched versions of these products
  • ·Debian WebKitGTK fix landed in version 2.18.1-1 across all tracked branches (bookworm, bullseye, forky, sid, trixie) — Linux environments running older WebKitGTK are also in scope
