DescriptionCVE.org
External control of file name or path in Windows Kernel allows an authorized attacker to elevate privileges locally.
Executive ViewAI
A high-severity Windows Kernel vulnerability (CVE-2026-24287) allows authorized users to gain elevated system privileges on affected endpoints. With no patch currently available and a 7.8 CVSS score, this poses a significant risk to organizations where insider threats or compromised user accounts could lead to unauthorized administrative access across critical systems.
Monitor and restrict user privileges to least-privilege principles; implement Application Whitelisting to prevent unauthorized process execution; enable and audit Windows Event Log monitoring for privilege escalation attempts (Event IDs 4672, 4673); use filesystem monitoring tools to detect suspicious file path manipulation; apply defense-in-depth via Code Integrity/Secure Boot; restrict file system permissions on sensitive directories; consider isolating highest-risk systems until patch is available.
