ubuntu
Calendar Grey April 24, 2025
Dist Ubuntu Esm H88
Multiple vulnerabilities resolved in Ubuntu 18.04 LTS pertaining to the IBM kernel. Key patches address denial-of-service and execution vulnerabilities.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-ibm-5.4: Linux kernel for IBM cloud systems

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)

Attila Szász discovered that the HFS+ file system implementation in the

Linux Kernel contained a heap overflow vulnerability. An attacker could use

a specially crafted file system image that, when mounted, could cause a

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

(CVE-2025-0927)

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:

- PowerPC architecture;

- S390 architecture;

- SuperH RISC architecture;

- User-Mode Linux...

Update Instructions

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

Ubuntu 18.04 LTS
  linux-image-5.4.0-1090-ibm      5.4.0-1090.95~18.04.1
                                  Available with Ubuntu Pro
  linux-image-ibm                 5.4.0.1090.95~18.04.1
                                  Available with Ubuntu Pro

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.
