CVE-2001-1560

Status: ModifiedLow (2.1)—💥 Exploit

Win32k.sys (aka Graphics Device Interface (GDI)) in Windows 2000 and XP allows local users to cause a denial of service (system crash) by calling the ShowWindow function after receiving a WM_NCCREATE message.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:N/I:N/A:P
Base score: 2.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 3.07%
Percentile among all scored CVEs: 87
Score date: 10/7/2026

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
