CVE-2025-24258 is a permissions-related vulnerability in Apple macOS that allows an application to gain root privileges improperly. The root cause is a permissions issue that was addressed by Apple through additional restrictions in the latest security updates. The vulnerability affects multiple macOS versions, including Sequoia prior to 15.4, Sonoma prior to 14.7.6, and Ventura prior to 13.7.6. The CVSS 3.1 base score is 7.8, indicating high severity, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This means the attack requires local access (AV:L), low attack complexity (AC:L), privileges at a low level (PR:L), no user interaction (UI:N), unchanged scope (S:U), and results in high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability falls under CWE-269 (Improper Privilege Management), highlighting that the system failed to enforce proper privilege restrictions. Although no public exploits are known, the vulnerability enables an attacker with limited privileges to escalate to root, potentially compromising the entire system. Apple has released patches in the specified macOS versions to remediate this issue. The vulnerability was reserved in January 2025 and published in May 2025, indicating a recent discovery and disclosure.

If exploited, this vulnerability allows an attacker with local access and limited privileges to escalate to root privileges, gaining full control over the affected macOS system. This compromises confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by potentially disabling system functions or deploying destructive payloads. The lack of required user interaction and low attack complexity increase the risk of exploitation in environments where local access is possible, such as shared workstations or multi-user systems. Organizations relying on macOS for critical operations, development, or infrastructure management face significant risks including data breaches, system takeovers, and lateral movement within networks. The vulnerability could also be leveraged by malware or advanced persistent threats to maintain persistence and evade detection. Although no known exploits are currently reported, the potential impact warrants urgent patching and monitoring.

1. Immediately apply the security updates provided by Apple for macOS Sequoia 15.4, Sonoma 14.7.6, and Ventura 13.7.6 or later versions to remediate the vulnerability. 2. Restrict local access to macOS systems by enforcing strong physical and logical access controls, including multi-factor authentication and least privilege principles. 3. Monitor system logs and behavior for unusual privilege escalations or suspicious activities indicative of exploitation attempts. 4. Employ endpoint detection and response (EDR) solutions capable of detecting privilege escalation techniques on macOS platforms. 5. Limit the installation and execution of untrusted or unnecessary applications to reduce the attack surface. 6. Conduct regular security audits and vulnerability assessments focused on privilege management and access controls. 7. Educate users about the risks of running untrusted software and the importance of reporting anomalies promptly. 8. For environments with high security requirements, consider implementing macOS security features such as System Integrity Protection (SIP) and mandatory access controls to further restrict privilege escalation paths.
