An information leakage was addressed with additional validation. This issue is fixed in macOS Tahoe 26.5. An app may be able to gain root privileges.
AI Analysis
Technical Summary
This vulnerability in Apple macOS involves an information leakage flaw that could be leveraged by an application to escalate privileges to root. The issue was mitigated by adding validation checks. It affects macOS versions prior to the fixed release, macOS Tahoe 26.5. The CVSS 3.1 base score of 7.5 reflects a network attack vector with low attack complexity, no privileges required, and no user interaction needed, resulting in high confidentiality impact but no integrity or availability impact.
Potential Impact
An attacker could exploit this vulnerability to gain root privileges on a vulnerable macOS system, potentially leading to unauthorized full control over the system. The confidentiality impact is high due to information leakage, but there is no direct integrity or availability impact reported. No known exploits are currently active in the wild.
Mitigation Recommendations
This vulnerability is fixed in macOS Tahoe 26.5. Users and administrators should update to this version or later to remediate the issue. Patch status is not explicitly confirmed beyond the mention of the fix in macOS Tahoe 26.5; therefore, verify with Apple's official advisory for the latest remediation guidance.
