Ubuntu Security Notice USN-6956-1
August 12, 2024
linux-azure, linux-azure-5.15, linux-azure-fde, linux-azure-fde-5.15
vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
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.

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.
