USN-7008-1: Linux kernel vulnerabilities

Releases

• Ubuntu 22.04 LTS

Packages

• linux-lowlatency-hwe-6.8 - Linux low latency kernel

Details

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2024-23848)

It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash). (CVE-2024-40902)

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-6.8.0-44-lowlatency - 6.8.0-44.44.1~22.04.1
• linux-image-6.8.0-44-lowlatency-64k - 6.8.0-44.44.1~22.04.1
• linux-image-lowlatency-64k-hwe-22.04 - 6.8.0-44.44.1~22.04.1
• linux-image-lowlatency-hwe-22.04 - 6.8.0-44.44.1~22.04.1

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.
