Lifecycle Timeline
4Description
This issue was addressed by removing the vulnerable code. This issue is fixed in tvOS 18.4.1, visionOS 2.4.1, iOS iOS 18.4.1 and iPadOS 18.4.1, macOS Sequoia 15.4.1. 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.
Analysis
Apple devices contain a vulnerability allowing attackers with arbitrary read/write to bypass Pointer Authentication Codes (PAC), addressed by removing the vulnerable code. Exploited alongside CVE-2025-31200.
Technical Context
The CWE-1220 insufficient granularity of access control in the PAC implementation allows bypassing the hardware-based code pointer integrity mechanism. This is a critical post-exploitation primitive that neutralizes Apple's primary defense against code reuse attacks.
Affected Products
['Apple tvOS before 18.4.1', 'Apple visionOS before 2.4.1', 'Apple iOS/iPadOS before 18.4.1', 'Apple macOS Sequoia before 15.4.1']
Remediation
Update all Apple devices immediately. Apple's approach of removing the vulnerable code indicates the feature was fundamentally flawed rather than simply missing a check.
