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.
