Local privilege escalation via untrusted pointer dereference
Published Oct 14, 2025 · Updated Oct 14, 2025
Untrusted pointer dereference in the Windows Kernel allows local users with low privileges to elevate their privileges on affected systems. Microsoft identifies improper input validation and an untrusted pointer dereference but has not disclosed the pointer source, affected function, or dereference operation. A local low-privileged account is required; the published record does not state the exact privilege level gained.
