Scroller Ubuntu
Ubuntu 22.04 LTS security update USN-7009-1 addresses several kernel vulnerabilities within linux-generic-hwe-6.8.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- 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.

This update corrects flaws in the following subsystems:

- ARM64 architecture;

- MIPS architecture;

- PA-RISC architecture;

- PowerPC architecture;

- RISC-V architecture;

- User-Mode Linux (UML);

- x86 architecture;

- Block layer subsystem;

- AC...

security advisory denial of service kernel update Ubuntu system crash linux kernel CVE issues

Update Instructions

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

Ubuntu 22.04 LTS
  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.
