Kernel-memory disclosure via Wi-Fi bounds-check failure
Published Nov 21, 2025 · Updated Apr 2, 2026
Out-of-bounds read in Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows physically proximate attackers to read kernel memory. The Wi-Fi component fails to enforce a required memory bound before reading from kernel memory; Apple has not disclosed a narrower code locus or input field. Exploitation requires physical proximity, and the published impact is limited to reading outside the intended kernel-memory bounds.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
