Multiple potential security vulnerabilities in some Intel® Processors have been found which may allow information disclosure or may allow escalation of privilege. Intel is releasing microcode updates to mitigate this potential vulnerabilities.
Please pay attention that the fix for CVE-2022-33196 might require a firmware update.
CVE-2022-21216 (INTEL-SA-00700)
Insufficient granularity of access control in out-of-band
management in some Intel(R) Atom and Intel Xeon Scalable Processors
may allow a privileged user to potentially enable escalation of
privilege via adjacent network access.
CVE-2022-21233 (INTEL-SA-00657)
Improper isolation of shared resources in some Intel(R) Processors
may allow a privileged user to potentially enable information
disclosure via local access.
CVE-2022-33196 (INTEL-SA-00738)
Incorrect default permissions in some memory controller
configurations for some Intel(R) Xeon(R) Processors when using
Intel(R) Software Guard Extensions which may allow a privileged user
to potentially enable escalation of privilege via local access.
This fix may require a firmware update to be effective on some
processors.
CVE-2022-33972 (INTEL-SA-00730)
Incorrect calculation in microcode keying mechanism for some 3rd
Generation Intel(R) Xeon(R) Scalable Processors may allow a
privileged user to potentially enable information disclosure via
local acces
CVE-2022-38090 (INTEL-SA-00767)
Improper isolation of shared resources in some Intel(R) Processors
when using Intel(R) Software Guard Extensions may allow a privileged
user to potentially enable information disclosure via local access.
