DescriptionCVE.org
Null pointer dereference in Windows Performance Counters allows an authorized attacker to elevate privileges locally.
Executive ViewAI
A high-severity vulnerability in Windows Performance Counters enables authorized users to escalate privileges on affected systems. Without an available patch, this poses a material risk to organizations where local account compromise could lead to administrative access, potentially compromising sensitive data and critical system operations.
Restrict access to Windows Performance Counters through Group Policy (disable performance monitoring for non-admin users); limit local administrative account usage; enforce multi-factor authentication for privileged accounts; deploy behavioral monitoring/EDR to detect privilege escalation attempts; isolate critical systems via network segmentation; disable Performance Counters service where operationally acceptable; implement account enumeration controls to limit user reconnaissance.

Priority Score
Attack Technique
A null pointer dereference occurs when a program attempts to access memory through a pointer that has been set to NULL (address 0x0).
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
