microcode side fixes and mitigations for at least the following security
issues:

A flaw was found in the implementation of SGX around the access control
of protected memory. A local attacker of a system with SGX enabled and
an affected intel GPU with the ability to execute code is able to infer
the contents of the SGX protected memory (CVE-2019-0117).

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).

Improper conditions check in the voltage modulation interface for some
Intel(R) Xeon(R) Scalable Processors may allow a privileged user to
potentially enable denial of service via local access (CVE-2019-11139).

Improper invalidation for page table updates by a virtual guest operating
system for multiple Intel(R) Processors may allow an authenticated user to
potentially enable denial of service of the host system via local access
(CVE-2018-12207).

TA Indirect Sharing Erratum (Information Leak)

Incomplete fixes for previous MDS mitigations (VERW)

SHUF* instruction implementation flaw (DoS)

EGETKEY Erratum

Conditional Jump Macro-fusion (DoS or Privilege Escalation)

For the software side fixes and mitigations of these issues, the kernel
must be updated to 5.3.13-1.mga7 (mga$?25686) or later.");
