ubuntu
Calendar Grey November 12, 2024
Dist Ubuntu Esm H88
Several vulnerabilities within the Linux kernel have been fixed for Ubuntu 22.04 LTS. Users are advised to apply updates promptly.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

Details:

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.

This update corrects flaws in the following subsystems:

- ARM64 architecture;

- MIPS architecture;

- PowerPC architecture;

- RISC-V architecture;

- User-Mode Linux (UML);

- x86 architecture;

- Block layer subsystem;

- Android drivers;

- Serial ATA and Parallel ATA drivers;

- ATM drivers;

Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1072-aws     5.15.0-1072.78
  linux-image-aws-lts-22.04       5.15.0.1072.72

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.
