Earlier this month, AMD published the Radeon Software Adrenalin 2020 Edition 20.1.1 driver. This release added support for Monster Hunter World: Iceborne and fixed some bugs.
One thing that AMD didn't mention in the changelog is that they also patched four security vulnerabilities.
The vulnerabilities do not really concern gamers as the flaws as they concern virtual machines. Three of the flaws result in a crash of the graphics driver and the fourth flaw in AMD's shader compiler makes it possible to exploit the host machine of a VMWare virtual machine.
The first vulnerability, CVE-2019-5146, is briefly described as "AMD ATI Radeon ATIDXX64.DLL MAD shader functionality denial-of-service vulnerability."
