Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Windows Kernel Elevation of Privilege Vulnerability CVE-2024-26218 affects the Windows kernel and carries a CVSS 7.8 score reflecting local attack vector, low attack complexity, and low privileges required. The associated CWEs include CWE-367, indicating a time-of-check to time-of-use race condition class of flaw.
An authenticated local attacker can exploit the issue without user interaction to elevate privileges and obtain full control over confidentiality, integrity, and availability on the affected system. The published EPSS score has reached a peak of 0.3263 with a current value of 0.2715, indicating measurable post-disclosure interest in exploitation.
Microsoft has published guidance for the vulnerability in its security update catalog at the referenced advisory URL, which practitioners should consult for available patches and configuration steps.

Mitigating Controls (NIST 800-53 r5) AI
A reference monitor that is always invoked and analyzable structurally eliminates the non-atomic check-then-use pattern underlying TOCTOU.
Access enforcement that performs an atomic check-and-use decision directly stops the window in which a TOCTOU race can be exploited.
Process isolation limits the blast radius of a successful TOCTOU exploitation but does not remove the race itself.
