Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
