Ubuntu Security Notice USN-7033-1
September 25, 2024

intel-microcode vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in Intel Microcode.

Software Description:
- intel-microcode: Processor microcode for Intel CPUs

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)

The problem can be corrected by updating your system to the following
package versions:
