USN-4385-1 provided updated Intel Processor Microcode. Unfortunately,
that update prevented certain processors in the Intel Skylake family
(06_4EH) from booting successfully. Additonally, on Ubuntu 20.04
LTS, late loading of microcode was enabled, which could lead to
system instability. This update reverts the microcode update for
the Skylake processor family and disables the late loading option on
Ubuntu 20.04 LTS.
Please note that the 'dis_ucode_ldr' kernel command line option can be
added in the boot menu to disable microcode loading for system recovery.
We apologize for the inconvenience.

CVE-2020-0548 [MEDIUM] CWE-203 hw: Vector Register Data Sampling
hw: Vector Register Data Sampling
Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read by another process or a CPU sibling. The highest threat from this vulnerability is data confidentiality where an attacker could read arbitrary data as it passes through the processor.
