CVE-2021-25701
The fUSBHub driver in the PCoIP Software Client prior to version 21.07.0 had an error in object management during the handling of a variety of IOCTLs, which allowed an attacker to cause a denial of service.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
