Executive Summary

This vulnerability is an out-of-bounds read in kernel memory that occurs due to insufficient bounds checking. It can be triggered by an attacker who is physically close to the device, potentially causing the system to read memory outside the intended boundaries.

Impact Analysis

An attacker in physical proximity could exploit this vulnerability to cause an out-of-bounds read in kernel memory, which may lead to information disclosure or system instability, potentially compromising the security and reliability of the affected device.

Mitigation Strategies

Apply the security updates provided by Apple for your device's operating system as soon as possible. Specifically, update to iPadOS 17.7.7, iOS 18.5, iPadOS 18.5, visionOS 2.5, macOS Sonoma 14.7.3, macOS Ventura 13.7.3, macOS Sequoia 15.5, or watchOS 11.5 depending on your device. Since the vulnerability requires physical proximity, also limit physical access to your devices to untrusted individuals.
