Local privilege escalation via improper link resolution
Published Apr 11, 2023 · Updated Jan 23, 2025
Improper link resolution in Microsoft Windows Kernel allows local users with low privileges to gain elevated privileges. Microsoft identifies link following before file access but has not disclosed the kernel routine, object path, or link target involved. Exploitation requires local low-privilege access and no user interaction; successful use permits system modification and service interruption, not direct data disclosure.
