This vulnerability can be exploited by an attacker with valid credentials to gain elevated privileges and execute arbitrary code."
Anticipated Attack Path
- 1. Initial Exploitation: Authorized attacker exploits double free vulnerability
- 2. Privilege Escalation: Attacker gains elevated privileges
- 3. Post-Exploitation: Attacker executes arbitrary code and gains unauthorized access
Am I Vulnerable?
- Verify system logs for suspicious activity
- Monitor system for unusual privilege escalations
- Apply security patches and updates to the Windows Kernel
