CVE-2023-46103 [MEDIUM] Intel Microcode vulnerabilities
Title: Intel Microcode vulnerabilities
Summary: Several security issues were fixed in Intel Microcode.
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, Ubunt

kernel: local privilege escalation on Intel microcode on Intel(R) Xeon(R)
Protection mechanism failure in some 3rd and 4th Generation Intel(R) Xeon(R) Processors when using Intel(R) SGX or Intel(R) TDX may allow a privileged user to potentially enable escalation of privilege via local access.
A vulnerability was found in the Intel Xeon Processor's microcode. This issue may allow a malicious actor to achieve local privilege escalation when using Intel SGX or Intel TDX features.
