========================================================================== Ubuntu Security Notice USN-4694-1 January 14, 2021
linux, linux-hwe, linux-hwe-5.4, linux-hwe-5.8, linux-lts-xenial vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 ESM
Summary:
The system could allow unintended access to data in some environments.
Software Description: - linux: Linux kernel - linux-hwe-5.8: Linux hardware enablement (HWE) kernel - linux-hwe-5.4: Linux hardware enablement (HWE) kernel - linux-hwe: Linux hardware enablement (HWE) kernel - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
Details:
It was discovered that the LIO SCSI target implementation in the Linux kernel performed insufficient identifier checking in certain XCOPY requests. An attacker with access to at least one LUN in a multiple backstore environment could use this to expose sensitive information or modify data.
Update instructions:
The problem can be corrected by updating your system to the following package versions:

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.
