CVE-2025-60720
📋 TL;DR
A buffer over-read vulnerability in Windows TDX.sys allows an authenticated attacker to read beyond allocated memory boundaries, potentially leading to local privilege escalation. This affects Windows systems with the vulnerable driver component. Attackers must already have local access to exploit this vulnerability.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM privileges, enabling installation of persistent malware, credential theft, and lateral movement across the network.
Likely Case
Local privilege escalation from standard user to administrator/SYSTEM level, allowing installation of additional malware or bypassing security controls.
If Mitigated
Limited impact due to proper access controls, application whitelisting, and network segmentation preventing lateral movement.
🎯 Exploit Status
Requires local authenticated access and knowledge of memory layout. Buffer over-read vulnerabilities typically require additional steps to achieve reliable exploitation.
