Details

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)
