Local privilege escalation via registry link resolution
Published Dec 12, 2023 · Updated Jan 1, 2025
Improper link resolution in Windows Kernel in Windows allows local users to gain elevated privileges via a crafted registry operation. The kernel follows attacker-controlled registry links without enforcing the intended target, enabling writes or access under higher privileges. Exploitation requires a local authenticated account and can grant SYSTEM-level control, affecting confidentiality, integrity, and availability.
