Local privilege escalation via unrestricted raw disk access

Improper access control in EaseUS Partition Master 14.0 through 14.5 allows local users to read and write protected disk data. The EUEDKEPM.sys kernel driver exposes a caller-selected disk device to standard users and forwards raw reads and writes without enforcing Windows access checks. Medium-integrity local access is sufficient to bypass file and raw-disk permissions, enabling protected-data disclosure or tampering and privilege escalation when modified data controls privileged code or configuration.
