Analysis

AI-generated

Technical impact

An authentication flaw in macOS permits a malicious or vulnerable application to trigger unexpected system termination, effectively taking the operating system offline. This improper authentication weakness (CWE‑287) results in a denial of service.

Affected Systems

Apple macOS releases earlier than macOS Golden Gate 27, Sequoia 15.8, or Tahoe 26.6 are affected. These versions lack the improved authentication routine that was introduced in the specified fix releases, so any system running those earlier is susceptible to the termination flaw.

Risk and Exploitability

The CVSS score of 7.5 indicates a high severity, while the EPSS score (< 1 %) and absence from the CISA KEV catalog suggest a low probability of active exploitation at present. The exploit appears to require a local application or privileged process that can trigger the flawed authentication routine; no documented remote attack vector exists.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to macOS Golden Gate 27, Sequoia 15.8, Tahoe 26.6, or any newer release where the authentication improvement is included
  • If an upgrade cannot be applied immediately, restrict installation of unknown or untrusted applications that may trigger the authentication flaw
  • Examine and harden local authentication settings to prevent improper authentication attempts that could lead to system termination
