Microsoft has shed light on a now-patched security flaw impacting Apple macOS that, if successfully exploited, could have allowed an attacker running as "root" to bypass the operating system's System Integrity Protection (SIP) and install malicious kernel drivers by loading third-party kernel extensions.

The vulnerability in question is CVE-2024-44243 (CVSS score: 5.5), a medium-severity bug that was addressed by Apple as part of macOS Sequoia 15.2 released last month. The iPhone maker described it as a "configuration issue" that could permit a malicious app to modify protected parts of the file system.
