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.

Improper input validation for some Intel(R) PROSet/Wireless WiFi, Intel vPro(R) CSME WiFi and Killer(TM) WiFi products may allow unauthenticated user to potentially enable denial of service via local access.

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.

Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially cause a denial of service via local access.

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.

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Insufficient access control in protected memory subsystem for Intel(R) TXT for 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Xeon(R) Processor E3-1500 v5 and v6 Families; Intel(R) Xeon(R) E-2100 and E-2200 Processor Families with Intel(R) Processor Graphics and Intel(R) TXT may allow a privileged user to potentially enable information disclosure via local access.
