CVE-2022-24138
Low privilege users can use SetOpLock to wait for CreateProcess and switch the genuine component with a malicious executable thus gaining code execution as a high privilege user (Low Privilege -> high integrity ADMIN).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.58%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
