  - Intel reports: 2024.1 IPU - Intel Processor Bus Lock Advisory A potential security vulnerability in the
    bus lock regulator           mechanism for some Intel Processors may allow denial of service. Intel
    is releasing firmware updates to mitigate this potential           vulnerability. 2024.1 IPU - Intel
    Processor Return Predictions Advisory A potential security vulnerability in some Intel Processors may
    allow information disclosure. 2024.1 IPU - Intel Atom Processor Advisory A potential security
    vulnerability in some Intel Atom Processors           may allow information disclosure. 2024.1 IPU - Intel
    Xeon Processor Advisory A potential security vulnerability in some 3rd and 4th Generation           Intel
    Xeon Processors when using Intel Software Guard Extensions (SGX)           or Intel Trust Domain
    Extensions (TDX) may allow escalation of           privilege. 2024.1 IPU OOB - Intel Xeon D Processor
    Advisory A potential security vulnerability in some Intel Xeon D Processors           with Intel Software
    Guard Extensions (SGX) may allow information           disclosure. (CVE-2023-22655, CVE-2023-43490)

  - This CVE was assigned by Intel. Please see CVE-2023-28746 on CVE.org for more information.
    (CVE-2023-28746)

  - Non-transparent sharing of return predictor targets between contexts in some Intel Processors may allow
    an authorized user to potentially enable information disclosure via local access. (CVE-2023-38575)
    (CVE-2023-38575, CVE-2023-39368)
