This could lead to local escalation of privilege revealing the user's keypresses while the screen was locked with no additional execution privileges needed.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
