CVE-2026-34334
HighSummary
A race condition in Windows TCP/IP allows for concurrent execution using shared resources with improper synchronization. This enables an authorized attacker to elevate privileges locally.
Risk Assessment
This vulnerability can be exploited by local users to gain higher privileges, posing a significant security risk to the system.
Recommendation
It is recommended to update Windows to the latest version to mitigate this vulnerability and to monitor system access for unauthorized activities.
