Summary
intel-microcode vulnerabilities
Details

Avraham Shalev and Nagaraju N Kodalapura discovered that some Intel(R) Xeon(R) processors did not properly restrict access to the memory controller when using Intel(R) SGX. This may allow a local privileged attacker to further escalate their privileges. (CVE-2024-21820, CVE-2024-23918)

It was discovered that some 4th and 5th Generation Intel(R) Xeon(R) Processors did not properly implement finite state machines (FSMs) in hardware logic. THis may allow a local privileged attacker to cause a denial of service (system crash). (CVE-2024-21853)

It was discovered that some Intel(R) Processors did not properly restrict access to the Running Average Power Limit (RAPL) interface. This may allow a local privileged attacker to obtain sensitive information. (CVE-2024-23984)

It was discovered that some Intel(R) Processors did not properly implement finite state machines (FSMs) in hardware logic. This may allow a local privileged attacker to cause a denial of service (system crash). (CVE-2024-24968)
