Ubuntu Security Notice USN-6952-2
August 13, 2024

linux-azure vulnerabilities
==========================================================================

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

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-azure: Linux kernel for Microsoft Azure 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 24.04 LTS
   linux-image-6.8.0-1012-azure    6.8.0-1012.14
   linux-image-6.8.0-1012-azure-fde  6.8.0-1012.14
   linux-image-azure               6.8.0-1012.14
   linux-image-azure-fde           6.8.0-1012.14

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.
