CVE-2021-0145 [MEDIUM] Intel Microcode vulnerabilities
Title: Intel Microcode vulnerabilities
Summary: Several security issues were fixed in Intel Microcode.
Joseph Nuzman discovered that some Intel processors did not properly
initialise shared resources. A local attacker could use this to obtain
sensitive information. (CVE-2021-0145)
Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel
processors did not prevent test and debug logic from being activated at
runtime. A local attacker could use this to escalate
privileges. (CVE-2021-0146)
It was discovered that some Intel processors did not implement sufficient
control flow management. A local attacker could use this to cause a denial
of service (system crash). (CVE-2021-0127)

microcode: Intel Processor Breakpoint Control Flow
Insufficient control flow management in some Intel(R) Processors may allow an authenticated user to potentially enable a denial of service via local access.
A flaw was found in microcode. Under complex microarchitectural conditions, an unexpected code breakpoint may cause a system hang. The hang was observed on a Skylake server processor, and subsequent analysis indicated additional potentially affected processors. This flaw allows a possible temporary denial of service (TDOS) to occur.
Statement: Red Hat has very limited to no visibility and control over binary blobs provided by third-party vendors. Red Hat relies heavily on the vendors to provide timely updates and information about included changes for this content. In most cases, it
