intel-microcode vulnerabilities

Published Dec 11, 2024 · Updated Jun 25, 2026

Ecosystem: Ubuntu

Summary

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)
