Summary
A time-of-check time-of-use race condition in Windows Kernel Memory 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 | 7.8 | CVE-2026-20809 |
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, the attacker can manipulate the timing of operations to gain elevated privileges. This can be done by executing a series of carefully timed actions that exploit the flaw in the kernel’s memory management.
Affected Products
- Windows Kernel Memory: Vulnerable to privilege escalation due to a race condition.
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, implementing strict access controls can limit the potential for unauthorized access.
