Ubuntu Security Notice USN-5857-1
February 09, 2023

linux-oem-6.0 vulnerability

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

– Ubuntu 22.04 LTS


The system could be made to crash or run programs as an administrator.

Software Description:
– linux-oem-6.0: Linux kernel for OEM systems


Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel
did not properly handle VLAN headers in some situations. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code.

Update instructions:

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

Ubuntu 22.04 LTS:
linux-image-6.0.0-1011-oem 6.0.0-1011.11

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.
