Network privilege escalation via shared-resource race
Published Sep 8, 2026 · Updated Sep 10, 2026
A race condition in Windows Print Spooler Components allows remote authenticated users to elevate privileges over a network. The spooler permits concurrent execution against a shared resource without proper synchronization, creating a timing window. Reachability requires authorized network access and control of the race; Microsoft has not disclosed the shared resource or resulting privilege level.
