USN-8185-1: Linux kernel (NVIDIA) vulnerabilities
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign and a privileged attacker could possibly use it to load malicious CPU microcode causing loss of integrity and confidentiality.

USN-8177-2: Linux kernel (Real-time) vulnerabilities
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign and a privileged attacker could possibly use it to load malicious CPU microcode causing loss of integrity and confidentiality.
