CVE-2023-36759

Local privilege escalation via pgodriver.sys pointer dereference

Published Sep 12, 2023 · Updated Oct 30, 2025

Untrusted pointer dereference in affected Microsoft Visual Studio 2019 and 2022 releases allows local users to elevate privileges. The pgodriver.sys kernel driver dereferences an attacker-influenced pointer while reading a malicious file; Microsoft has not identified the affected routine or resulting memory primitive. Exploitation requires local access, low privileges, user interaction, and delivery of a malicious file; the published record does not identify the elevated security context.
