Impact
A buffer overflow in WebKitGTK occurs when the browser processes maliciously crafted web content. The flaw corrupts memory during parsing, causing the rendering process to crash. The crash results in a denial‑of‑service condition for the affected system."
Affected Systems
Apple products – Safari, iOS, iPadOS, macOS Sequoia, tvOS and watchOS – are vulnerable in versions up to Safari 18.4, iOS 18.4, iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, tvOS 18.4 and watchOS 11.4. CPE data also lists several Red Hat Enterprise Linux releases (RHEL 8, 9 and related extended‑support streams), indicating that WebKitGTK derivatives on those platforms may also be affected, although no explicit vendor patch level is provided.
Risk and Exploitability
The CVSS score of 7 marks this as high severity, while the EPSS score of <1% indicates a low likelihood of exploitation in the near term. The vulnerability is not listed in CISA’s KEV catalog, so no widely deployed exploit is known. The attack vector is presumably remote; an attacker may trigger the crash by delivering crafted HTML or JavaScript to a browser or WebKitGTK‑based application that processes the malicious content.
