Software Description:

- linux-raspi: Linux kernel for Raspberry Pi systems

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

Details:

It was discovered that the CIFS network file system implementation in the

Linux kernel did not properly verify the target namespace when handling

upcalls. An attacker could use this to expose sensitive information.

(CVE-2025-2312)

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:

Update Instructions

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

Ubuntu 20.04 LTS
   linux-image-5.4.0-1130-raspi    5.4.0-1130.143
                                   Available with Ubuntu Pro
   linux-image-raspi               5.4.0.1130.161
                                   Available with Ubuntu Pro
   linux-image-raspi2              5.4.0.1130.161
                                   Available with Ubuntu Pro

Ubuntu 18.04 LTS
   linux-image-5.4.0-1130-raspi    5.4.0-1130.143~18.04.1
                                   Available with Ubuntu Pro
   linux-image-raspi-hwe-18.04     5.4.0.1130.143~18.04.1
                                   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.
