- intel-microcode: Processor microcode for Intel CPUs
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. (CVE-2017-5715)
This update provides the corrected microcode updates required for the
corresponding Linux kernel updates.
The problem can be corrected by updating your system to the following
