CVE-2025-50892 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
