CVE-2025-50892 (GCVE-0-2025-50892)

Vulnerability from cvelistv5 – Published: 2025-09-10 00:00 – Updated: 2026-07-05 01:11

Summary

The eudskacs.sys driver version 20250328 shipped with EaseUs Todo Backup 1.2.0.1 fails to properly validate privileges for I/O requests (IRP_MJ_READ/IRP_MJ_WRITE) sent to its device object. This allows a local, low-privileged attacker to perform arbitrary raw disk reads and writes, leading to sensitive information disclosure, denial of service, or local privilege escalation.

Severity

7.8 (High)
