    It was discovered that some 3rd and 4th Generation Intel Xeon Processors did not properly restrict     access to certain hardware features when using Intel SGX or Intel TDX. This may allow a privileged     local user to potentially further escalate their privileges on the system. This issue only affected Ubuntu     23.10, Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. (CVE-2023-22655)

    It was discovered that some Intel Atom Processors did not properly clear register state when     performing various operations. A local attacker could use this to obtain sensitive information via a     transient execution attack. This issue only affected Ubuntu 23.10, Ubuntu 22.04 LTS, Ubuntu 20.04 LTS,     Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. (CVE-2023-28746)

    It was discovered that some Intel Processors did not properly clear the state of various hardware     structures when switching execution contexts. A local attacker could use this to access privileged     information. This issue only affected Ubuntu 23.10, Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS     and Ubuntu 16.04 LTS. (CVE-2023-38575)

    It was discovered that some Intel Processors did not properly enforce bus lock regulator protections. A     remote attacker could use this to cause a denial of service. This issue only affected Ubuntu 23.10, Ubuntu     22.04 LTS, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. (CVE-2023-39368)

    It was discovered that some Intel Xeon D Processors did not properly calculate the SGX base key when     using Intel SGX. A privileged local attacker could use this to obtain sensitive information. This issue     only affected Ubuntu 23.10, Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2023-43490)

    It was discovered that some Intel Processors did not properly protect against concurrent accesses. A     local attacker could use this to obtain sensitive information. (CVE-2023-45733)

    It was discovered that some Intel Processors TDX module software did not properly validate input. A     privileged local attacker could use this information to potentially further escalate their privileges on     the system. (CVE-2023-45745, CVE-2023-47855)

    It was discovered that some Intel Core Ultra processors did not properly handle particular     instruction sequences. A local attacker could use this issue to cause a denial of service.
