Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
The kernel driver, accessible to low-privileged users, exposes a function that fails to properly validate the privileges of the calling process. This allows creating files at arbitrary locations with full user control, ultimately allowing for privilege escalation to SYSTEM.
