An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:

  • Hardware crypto device drivers;
  • NVIDIA Tegra memory controller driver;
  • Network drivers;
  • GFS2 file system;
  • OCFS2 file system;
  • SMB network file system;
  • B.A.T.M.A.N. meshing protocol;
  • Ceph Core library;
  • IPv4 networking;
  • IPv6 networking;
  • Netfilter;
  • Open vSwitch;
  • RxRPC session sockets;

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:

Ubuntu Release Package Version
24.04 LTS noble linux-image-6.17.0-1032-nvidia –  6.17.0-1032.32
linux-image-6.17.0-1032-nvidia-64k –  6.17.0-1032.32
linux-image-nvidia-6.17 –  6.17.0-1032.32
linux-image-nvidia-64k-6.17 –  6.17.0-1032.32
linux-image-nvidia-64k-hwe-24.04 –  6.17.0-1032.32
linux-image-nvidia-hwe-24.04 –  6.17.0-1032.32
