CVE-2020-28922
The PCADRVX64.SYS kernel driver exposes IOCTL functionality that allows low-privilege users to read and write arbitrary physical memory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
