CVE-2026-86958: macOS pointer authentication bypass with memory write capability

CVE-2026-86958 · Severity: info · Published 2026-10-26

An attacker with the ability to write to memory can bypass pointer authentication codes on macOS systems, allowing them to run arbitrary code. Pointer authentication is a security mechanism that prevents attackers from hijacking program execution. This vulnerability could lead to complete system compromise if exploited by malicious software or a local attacker with memory access.

Technologies: Apple macOS Golden Gate, Apple macOS Sequoia. Vendors: Apple.

Technical details

A memory handling vulnerability in macOS allows an attacker with memory write capability to bypass pointer authentication codes (a hardware-based code integrity protection), enabling arbitrary code execution. The issue requires local memory write access and affects the kernel or system libraries. Fixes were deployed in macOS Golden Gate 27, Sequoia 15.8.2, and Tahoe 26.7.2 through improved memory handling.

Affected products

Apple macOS Golden Gate prior to 27
Apple macOS Sequoia prior to 15.8.2
Apple macOS Tahoe prior to 26.7.2
