USN-7100-2: Linux kernel vulnerabilities

Releases

• Ubuntu 22.04 LTS

Packages

• 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.

Update instructions

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

Ubuntu 22.04

• 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.
