Ubuntu Security Notice 5634-1 - Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service.

linux-oem-5.17 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

The system could be made to crash if it received specially crafted
network traffic.

Software Description:
- linux-oem-5.17: Linux kernel for OEM systems

Details:

Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter
subsystem in the Linux kernel did not properly handle rules that
truncated packets below the packet header size. When such rules are in
place, a remote attacker could possibly use this to cause a denial of
service (system crash).

Update instructions:

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

Ubuntu 22.04 LTS:
linux-image-5.17.0-1017-oem 5.17.0-1017.18
linux-image-oem-22.04 5.17.0.1017.16
linux-image-oem-22.04a 5.17.0.1017.16

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.
