Scroller Ubuntu
Numerous vulnerabilities in the Ubuntu kernel necessitate prompt upgrades to bolster system security and reliability.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems

- linux-azure-5.4: Linux kernel for Microsoft Azure cloud systems

- linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems

- linux-hwe-5.4: Linux hardware enablement (HWE) kernel

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

- linux-oracle-5.4: Linux kernel for Oracle Cloud systems

- linux-raspi-5.4: Linux kernel for Raspberry Pi systems

Details:

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:

- MIPS architecture;

- PowerPC architecture;

- x86 architecture;

- A...

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.
