CVE-2025-46310 is a security vulnerability identified in Apple macOS that allows an attacker possessing root privileges to delete protected system files. The root cause is linked to improper state management within the operating system, which fails to adequately safeguard critical system files from deletion even by privileged users. This vulnerability affects macOS versions prior to Sequoia 15.7.4 and Sonoma 14.8.4, where Apple has implemented fixes to improve state management and prevent unauthorized file deletions. The attack vector requires local access with root privileges, meaning an attacker must already have elevated permissions on the system. No user interaction is required to exploit this vulnerability. The impact primarily affects system integrity and availability, as deletion of protected files can cause system instability, malfunction, or denial of service conditions. The CVSS v3.1 base score is 6.0, reflecting a medium severity due to the requirement for high privileges and the absence of confidentiality impact. The vulnerability is classified under CWE-269 (Improper Privilege Management). No public exploits or active exploitation have been reported to date. Organizations running affected macOS versions should apply the security updates provided in macOS Sequoia 15.7.4 and Sonoma 14.8.4 to mitigate this risk.

The primary impact of CVE-2025-46310 is on system integrity and availability. An attacker with root access can delete protected system files, which may lead to system instability, malfunction, or complete denial of service. This could disrupt business operations, especially in environments where macOS is used for critical infrastructure, development, or production workloads. While confidentiality is not directly impacted, the loss of system files can cause significant downtime and recovery costs. The requirement for root privileges limits the scope of exploitation to scenarios where an attacker has already compromised the system or has insider access. However, in such cases, this vulnerability can be leveraged to escalate damage and complicate incident response. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often seek privilege escalation or post-compromise persistence techniques. Organizations relying heavily on macOS systems should consider this vulnerability a moderate risk that warrants timely patching to maintain system reliability and security.

1. Apply the official Apple security updates: Upgrade all affected macOS systems to at least Sequoia 15.7.4 or Sonoma 14.8.4 where the vulnerability is fixed. 2. Limit root access strictly: Enforce the principle of least privilege by restricting root account usage and monitoring for unauthorized privilege escalations. 3. Implement robust endpoint detection and response (EDR) solutions to detect unusual file deletion activities or privilege abuse. 4. Regularly back up critical system files and configurations to enable rapid recovery in case of file deletion or system corruption. 5. Conduct periodic audits of user privileges and system integrity to identify potential misuse or early signs of exploitation. 6. Use system integrity protection features provided by macOS to prevent unauthorized modifications to system files. 7. Educate system administrators and users about the risks of granting root access and encourage secure operational practices. 8. Monitor security advisories from Apple and threat intelligence sources for updates or emerging exploit information related to this vulnerability.
