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.

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 confidence

A denial-of-service vulnerability exists in message processing across multiple Apple platforms (iOS, iPadOS, macOS, tvOS, visionOS, watchOS). The vulnerability is triggered by processing a maliciously crafted message, and was remediated by removing the vulnerable code rather than patching it.
