ubuntu
Calendar Grey August 13, 2024
Dist Ubuntu Esm H88
A recent update addresses multiple vulnerabilities in the Linux kernel for both Ubuntu 22.04 and 20.04 LTS.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-azure: Linux kernel for Microsoft Azure Cloud systems

- linux-azure-fde: Linux kernel for Microsoft Azure CVM cloud systems

- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems

- linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems

Details:

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde

discovered that an untrusted hypervisor could inject malicious #VC

interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw

is known as WeSee. A local attacker in control of the hypervisor could use

this to expose sensitive information or possibly execute arbitrary code in

the trusted execution environment. (CVE-2024-25742)

Several security issues were discovered in the Linux kernel.

An attacker could possibly use these to compromise the system.

This update corrects flaws in the following subsystems:

- ARM32 architecture;

- ARM...

Update Instructions

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1070-azure   5.15.0-1070.79
   linux-image-5.15.0-1070-azure-fde  5.15.0-1070.79.1
   linux-image-azure-fde-lts-22.04  5.15.0.1070.79.47
   linux-image-azure-lts-22.04     5.15.0.1070.68

Ubuntu 20.04 LTS
   linux-image-5.15.0-1070-azure   5.15.0-1070.79~20.04.1
   linux-image-5.15.0-1070-azure-fde  5.15.0-1070.79~20.04.1.1
   linux-image-azure               5.15.0.1070.79~20.04.1
   linux-image-azure-cvm           5.15.0.1070.79~20.04.1
   linux-image-azure-fde           5.15.0.1070.79~20.04.1.47

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.
