Analyzing CVE-2024-44243, a macOS System Integrity Protection bypass through kernel extensions


Microsoft Threat Intelligence discovered a new macOS vulnerability that could allow attackers to bypass Apple’s System Integrity Protection (SIP) in macOS by loading third party kernel extensions.

SIP is a security technology that restricts the performance of operations that may compromise system integrity; thus, a SIP bypass affects the overall security of the operating system. Bypassing SIP could lead to serious consequences, such as increasing the potential for attackers and malware authors to successfully install rootkits, create persistent malware, bypass Transparency, Consent and Control (TCC), and expand the attack surface for additional techniques and exploits.
