USN-7931-5: Linux kernel (Raspberry Pi) vulnerabilities

Publication date: 9 January 2026
Overview: Several security issues were fixed in the Linux kernel.

Packages

• linux-raspi - Linux kernel for Raspberry Pi systems
• linux-raspi-realtime - Linux kernel for Raspberry Pi Real-time systems

Details
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:

• Cryptographic API;
• Media drivers;
• Memory management;
• Appletalk network protocol;
• Netfilter

Update instructions
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.

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

24.04 LTS noble

• linux-image-6.8.0-1044-raspi – 6.8.0-1044.48
• linux-image-6.8.0-2035-raspi-realtime – 6.8.0-2035.36
• linux-image-raspi – 6.8.0-1044.48
• linux-image-raspi-6.8 – 6.8.0-1044.48
• linux-image-raspi-realtime – 6.8.0-2035.36
• linux-image-raspi-realtime-6.8 – 6.8.0-2035.36
