CVE-2020-15479
The driver's IOCTL request handler attempts to copy the input buffer onto the stack without checking its size and can cause a buffer overflow.
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.
