USN-8508-1: Linux kernel (NVIDIA) vulnerabilities

Publication date

6 July 2026

Overview

Several security issues were fixed in the Linux kernel.

Releases

24.04 LTS

Packages

linux-nvidia-6.17 - Linux kernel for NVIDIA 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:

ARM64 architecture;
S390 architecture;
Block layer subsystem;
Cryptographic API;
DMA engine subsystem;
GPU drivers;
InfiniBand drivers;
Ethernet bonding driver;
STMicroelectronics network drivers;
Network drivers;
NVME drivers;
SCSI subsystem;
USB over IP driver;
File systems infrastructure;
Ext4 file system;
Network file system (NFS) server daemon;
SMB network file system;
Kernel thread helper (kthread);
Distributed Switch Architecture;
IPv6 networking;
Netfilter;
Tracing infrastructure;
Control group (cgroup);
Kernel exit() syscall;
Scatterlist API;

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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:
