Advisory Release Date: 2022-03-07 23:34 Pacific
Advisory Updated Date: 2022-03-08 18:12 Pacific
Severity:
Important
Issue Overview:
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. (CVE-2021-0127)
Hardware allows activation of test and debug logic at runtime for some Intel(R) processors which may allow an unauthenticated user to potentially enable escalation of privilege via physical access. (CVE-2021-0146)
Affected Packages:
