A series of vulnerabilities in the Linux kernel affecting Raspberry Pi have been resolved in Ubuntu, tackling significant risks and enhancing overall system reliability.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

It was discovered that the NVIDIA Tegra XUSB pad controller driver in the

Linux kernel did not properly handle return values in certain error

conditions. A local attacker could use this to cause a denial of service

(system crash). (CVE-2023-23000)

Quentin Minster discovered that the KSMBD implementation in the Linux

kernel did not properly handle session setup requests. A remote attacker

could possibly use this to cause a denial of service (memory exhaustion).

(CVE-2023-32247)

Lonial Con discovered that the netfilter subsystem in the Linux kernel did

not properly handle element deactivation in certain cases, leading to 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-2024-1085)

Notselwyn discovered that the netfilter...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1049-raspi   5.15.0-1049.52
   linux-image-raspi               5.15.0.1049.47
   linux-image-raspi-nolpae        5.15.0.1049.47

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.
