Summary
Concurrent execution using shared resource with improper synchronization in Microsoft Brokering File System allows an unauthorized 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 | 8.4 | CVE-2026-32091 |
Exploitation
To exploit this vulnerability, an attacker must have local access to the system. By executing concurrent processes that access shared resources without proper synchronization, the attacker can manipulate the execution flow to gain elevated privileges. This requires a low level of skill and can be performed without user interaction.
Affected Products
- Microsoft Brokering File System: Vulnerable to privilege escalation due to improper synchronization in concurrent execution.
Mitigation
To mitigate this vulnerability, it is recommended to apply the latest security updates provided by Microsoft. Additionally, restricting local access to sensitive systems can help reduce the risk of exploitation. Regularly reviewing and updating security policies can also enhance overall system security.
