It was discovered that a heap-based buffer overflow existed in the Marvell

WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could

use this to cause a denial of service (system crash) or possibly execute

arbitrary code. (CVE-2019-14895, CVE-2019-14901)

Update Instructions

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

Ubuntu 18.04 LTS:
  linux-image-5.3.0-26-generic    5.3.0-26.28~18.04.1
  linux-image-5.3.0-26-generic-lpae  5.3.0-26.28~18.04.1
  linux-image-5.3.0-26-lowlatency  5.3.0-26.28~18.04.1
  linux-image-generic-hwe-18.04   5.3.0.26.95
  linux-image-generic-lpae-hwe-18.04  5.3.0.26.95
  linux-image-lowlatency-hwe-18.04  5.3.0.26.95
  linux-image-snapdragon-hwe-18.04  5.3.0.26.95
  linux-image-virtual-hwe-18.04   5.3.0.26.95

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.
