Graphics Kernel

Summary

Concurrent execution using shared resource with improper synchronization in Graphics Kernel allows an authorized attacker to elevate privileges locally. This vulnerability can lead to significant security risks if exploited. Attackers can gain higher privileges than intended, potentially compromising system integrity.

Details

Severity Base Score CVE
HIGH 7 CVE-2026-20836

Exploitation

To exploit this vulnerability, an attacker must have local access to the system and be able to execute code. By taking advantage of the race condition in the Graphics Kernel, the attacker can manipulate the timing of operations to gain elevated privileges. This requires a high level of skill and knowledge of the system’s architecture.

Affected Products

  • Graphics Kernel: Vulnerable to privilege escalation due to improper synchronization.

Mitigation

To mitigate this vulnerability, it is recommended to apply the latest security updates provided by Microsoft. Regularly updating systems and monitoring for unusual activity can help reduce the risk of exploitation. Additionally, limiting local access to trusted users can further protect against potential attacks.
