MGASA-2022-0193

Summary: Updated microcode packages fix security vulnerabilities

Details: Updated microcodes for Intel processors, fixing various functional issues, and at least the following security issues: Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with SGX may allow an unprivileged user to potentially enable information disclosure via physical access (CVE-2022-0005). Description: Improper access control for some Intel(R) Xeon(R) Processors may allow an authenticated user to potentially enable information disclosure via local access (CVE-2022-21131). Improper input validation for some Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable denial of service via local access (CVE-2022-21136). Processor optimization removal or modification of security-critical code for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access (CVE-2022-21151). For info about the other fixes in this update, see the github reference.
