Apple Multiple Products Arbitrary Read and Write Vulnerability
Apple · Multiple Products
Apple's iOS, iPadOS, macOS, tvOS and visionOS contain an access control flaw classified as insufficient granularity of access control, which allowed code with arbitrary read and write capability to bypass Pointer Authentication. An attacker needs that arbitrary read and write capability first, and the vector indicates the flaw is reachable over the network with low complexity, requiring no privileges or user interaction.
This issue was addressed by removing the vulnerable code. This issue is fixed in iOS 18.4.1 and iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, visionOS 2.4.1. An attacker with arbitrary read and write capability may be able to bypass Pointer Authentication. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS.
