Issue Overview:
This security update is only applicable to EC2 Bare Metal instance types using Intel processors.
Intel has released microcode updates for certain Intel CPUs. After installing the updated microcode_ctl package, the microcode will be automatically activated on next boot.
Improper conditions check in the voltage modulation interface for some Intel Xeon Scalable Processors may allow a privileged user to potentially enable denial of service via local access.(CVE-2019-11139)
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.(CVE-2019-11135)
Affected Packages:
microcode_ctl, kernel
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
Issue Correction:
Run yum update microcode_ctl to update your system.
Run yum update kernel and reboot to update your system.
