intel-microcode vulnerabilities
Details

USN-7269-1 fixed vulnerabilities in Intel Microcode. This update provides the corresponding updates for Ubuntu 24.04 LTS.

Original advisory details:

Ke Sun, Paul Grosen and Alyssa Milburn discovered that some Intel® Processors did not properly implement Finite State Machines (FSMs) in Hardware Logic. A local privileged attacker could use this issue to cause a denial of service. (CVE-2024-31068)

It was discovered that some Intel® Processors with Intel® SGX did not properly restrict access to the EDECCSSA user leaf function. A local authenticated attacker could use this issue to cause a denial of service. (CVE-2024-36293)

Ke Sun, Alyssa Milburn, Benoit Morgan, and Erik Bjorge discovered that the UEFI firmware for some Intel® processors did not properly restrict access. An authenticated local attacker could use this issue to cause a denial of service. (CVE-2024-39279)
