Ubuntu 22.04 LTS USN-7123-1 critical: kernel issues affecting cloud systems

ubuntu
Calendar Grey November 20, 2024
Scroller Ubuntu
Essential patches for Ubuntu 22.04 LTS address several flaws in the Linux kernel, bolstering security measures for cloud environments on AWS.
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

Details:

It was discovered that the CIFS network file system implementation in the

Linux kernel did not properly validate certain SMB messages, leading to an

out-of-bounds read vulnerability. An attacker could use this to cause a

denial of service (system crash) or possibly expose sensitive information.

(CVE-2023-6610)

Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and

Shweta Shinde discovered that the Confidential Computing framework in the

Linux kernel for x86 platforms did not properly handle 32-bit emulation on

TDX and SEV. An attacker with access to the VMM could use this to cause a

denial of service (guest crash) or possibly execute arbitrary code.

(CVE-2024-25744)

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-5.15.0-1075-azure   5.15.0-1075.84
   linux-image-azure-lts-22.04     5.15.0.1075.73

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.
