Local privilege escalation via PPP EAP-TLS use-after-free
Published Aug 12, 2025 · Updated Feb 13, 2026
Use-after-free in Microsoft Windows PPP EAP-TLS allows local users to elevate privileges through an authorized local attack. Microsoft identifies the affected locus as Remote Access PPP EAP-TLS but has not disclosed which object is freed or later reused. Exploitation requires existing low-privilege access and user interaction and can grant elevated control over confidentiality, integrity, and availability.
