Improper access control in the firmware for some Intel(R) Processors may allow an unauthenticated user to potentially enable an escalation of privilege via local access.

Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)

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.

kernel: hw: Insecure default variable initialization for the Intel BSSA DFT feature

Insecure default variable initialization for the Intel BSSA DFT feature may allow a privileged user to potentially enable an escalation of privilege via local access.

hw: Vector Register Leakage-Active

Improper removal of sensitive information before storage or transfer in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

hw: Information disclosure issue in Intel SGX via RAPL interface

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

kernel: Insufficient access control vulnerability in PowerCap Framework

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.

Improper buffer restrictions in BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

hw: Load Value Injection

Load value injection in some Intel(R) Processors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. The list of affected products is provided in intel-sa-00334: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00334.html

hw: Vector Register Data Sampling

Cleanup errors in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

hw: Special Register Buffer Data Sampling (SRBDS)

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.

kernel: Intel graphics card information leak.

Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.

Improper conditions check in multiple Intel® Processors may allow an authenticated user to potentially enable partial escalation of privilege, denial of service and/or information disclosure via local access.

Improper conditions check in voltage settings for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege and/or information disclosure via local access.
