security advisory security issue Ubuntu kernel system update linux-hwe-5.15

Update Instructions

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

Ubuntu 20.04 LTS
   linux-image-5.15.0-136-generic  5.15.0-136.147~20.04.1
   linux-image-5.15.0-136-generic-64k  5.15.0-136.147~20.04.1
   linux-image-5.15.0-136-generic-lpae  5.15.0-136.147~20.04.1
   linux-image-generic-64k-hwe-20.04  5.15.0.136.147~20.04.1
   linux-image-generic-hwe-20.04   5.15.0.136.147~20.04.1
   linux-image-generic-lpae-hwe-20.04  5.15.0.136.147~20.04.1
   linux-image-oem-20.04           5.15.0.136.147~20.04.1
   linux-image-oem-20.04b          5.15.0.136.147~20.04.1
   linux-image-oem-20.04c          5.15.0.136.147~20.04.1
   linux-image-oem-20.04d          5.15.0.136.147~20.04.1
   linux-image-virtual-hwe-20.04   5.15.0.136.147~20.04.1

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.
