amd64-microcode - Processor microcode firmware for AMD CPUs

Details

Jann Horn discovered that microprocessors utilizing speculative execution
and branch prediction may allow unauthorized memory reads via sidechannel
attacks. This flaw is known as Spectre. A local attacker could use this to
expose sensitive information, including kernel memory.

This update provides the microcode updates for AMD 17H family
processors required for the corresponding Linux kernel updates.
