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

Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker can use this flaw to infer values returned by affected instructions known to be commonly used during cryptographic operations that rely on uniqueness, secrecy, or both.

micro-architecture specific Special Register Reads (SRR). On certain client and E3 processors,
the data returned by these SRR operations may be inferred, even on another core. Cleanup errors
from specific special register read operations may allow an authenticated user to potentially
enable information disclosure via local access.
Discussion:
Mitigation:
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
