Dist Ubuntu Esm H88
Ubuntu 20.04 LTS has released critical updates addressing vulnerabilities in the kernel that could potentially allow for denial of service and code execution threats if not addressed promptly.
Several security issues were fixed in the Linux kernel.

Summary

A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-intel-iotg-5.15: Linux kernel for Intel IoT platforms Details: Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32250, CVE-2023-32252, CVE-2023-32257) Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition.

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.15.0-1048-intel-iotg 5.15.0-1048.54~20.04.1 linux-image-intel 5.15.0.1048.54~20.04.38 linux-image-intel-iotg 5.15.0.1048.54~20.04.38 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
