Ubuntu 5346-1: Linux kernel (OEM) vulnerability | LinuxSecurity.com

Ubuntu Security Notice USN-5346-1

linux-oem-5.14 vulnerability
==========================================================================

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

- Ubuntu 20.04 LTS

Summary:

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

Software Description:
- linux-oem-5.14: Linux kernel for OEM systems

Details:

It was discovered that the ICMPv6 implementation in the Linux kernel did
not properly deallocate memory in certain situations. A remote attacker
could possibly use this to cause a denial of service (memory exhaustion).

Update instructions:

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

Ubuntu 20.04 LTS:
  linux-image-5.14.0-1029-oem     5.14.0-1029.32
  linux-image-oem-20.04           5.14.0.1029.26
  linux-image-oem-20.04b          5.14.0.1029.26
  linux-image-oem-20.04c          5.14.0.1029.26
  linux-image-oem-20.04d          5.14.0.1029.26

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.
