CVE-2026-45600

Status: AnalyzedHigh (7.8)—

Access of resource using incompatible type ('type confusion') in Windows Kernel-Mode Drivers allows an authorized attacker to elevate privileges locally.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques
