A vulnerability was identified in EaseUS Partition Master up to 14.5. The affected element is an unknown function in the library epmntdrv.sys of the component Kernel Driver. The manipulation leads to improper access controls. The attack needs to be performed locally. The exploit is publicly available and might be used. You should upgrade the affected component. The vendor explains: "We have confirmed that this issue was present only in older versions of the product. Our product has since been updated, and the issue has been resolved in the latest version, so it no longer exists."
