CVE-2024-44198
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn integer overflow was addressed through improved input validation. This issue is fixed in iOS 18 and iPadOS 18, macOS Sequoia 15, tvOS 18, visionOS 2, watchOS 11. Processing maliciously crafted web content may lead to an unexpected process crash.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA memory corruption vulnerability in WebKit (Apple's browser engine) where an integer overflow due to insufficient input validation can be triggered by processing maliciously crafted web content, leading to an unexpected process crash (denial of service).
