CVE-2025-43341 is a vulnerability identified in Apple macOS operating systems that stems from a permissions issue allowing an application with limited privileges to escalate its privileges to root level. Root privileges grant an attacker unrestricted control over the system, enabling them to modify system files, install persistent malware, and access sensitive data. The vulnerability was addressed by Apple through additional restrictions implemented in macOS Sonoma 14.8 and macOS Tahoe 26. The weakness falls under CWE-862, which relates to improper authorization, indicating that the system failed to enforce correct permission checks before granting elevated privileges. The CVSS v3.1 base score of 7.8 indicates a high-severity issue, with an attack vector requiring local access (AV:L), low attack complexity (AC:L), privileges required being low (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability presents a significant risk because it allows privilege escalation without user interaction, making it attractive for attackers who have already gained limited access to a system. The affected versions are prior to the patched releases, and the vulnerability's root cause is a failure to properly restrict permissions, allowing unauthorized privilege escalation.

If exploited, this vulnerability allows an attacker with local access and limited privileges to gain root-level control over the affected macOS system. This level of access compromises the confidentiality, integrity, and availability of the system and all data stored or processed on it. Attackers could install persistent malware, disable security controls, exfiltrate sensitive information, or disrupt system operations. For organizations, this could lead to data breaches, operational downtime, and loss of trust. The vulnerability is particularly critical in environments where macOS devices are used for sensitive tasks or hold critical data, such as in government, finance, healthcare, and technology sectors. Since exploitation does not require user interaction, automated or stealthy attacks are possible once local access is obtained, increasing the threat level. The lack of known exploits in the wild currently reduces immediate risk but does not diminish the urgency of patching, as attackers may develop exploits rapidly after public disclosure.

Organizations should immediately update all affected macOS systems to versions Sonoma 14.8 or Tahoe 26 or later, where the vulnerability is fixed. Beyond patching, restrict the installation and execution of untrusted or unnecessary applications to reduce the risk of local privilege escalation. Implement strict endpoint security controls, including application whitelisting and least privilege policies, to limit the ability of apps to gain elevated permissions. Monitor systems for unusual local activity that could indicate attempts to exploit privilege escalation. Employ robust logging and alerting mechanisms to detect suspicious privilege changes. For environments with high security requirements, consider additional hardening measures such as disabling unnecessary local accounts and restricting physical access to devices. Regularly review and audit user privileges and installed software to ensure compliance with security policies. Finally, educate users about the risks of running untrusted software, even locally, to reduce the attack surface.
