Kernel code execution via undisclosed DFS client flaw
Published Sep 13, 2022 · Updated Mar 11, 2025
Elevation of privilege in Microsoft Windows DFS allows local users to execute arbitrary code in the kernel through a vulnerable DFS client. Microsoft has not published the defective DFS routine or the incorrect operation it performs on attacker-controlled input. Exploitation requires a locally authenticated, low-privilege account and interaction with a vulnerable DFS client; success grants kernel-level code execution.
