USN-4253-1: Linux kernel vulnerability
28 January 2020
linux, linux-aws vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.10
Summary
The Linux kernel could be made to expose sensitive information.
Software Description
o linux - Linux kernel
o linux-aws - Linux kernel for Amazon Web Services (AWS) systems
Details
It was discovered that the Linux kernel did not properly clear data structures
on context switches for certain Intel graphics processors. A local attacker
could use this to expose sensitive information.
Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 19.10
linux-image-5.3.0-1010-aws - 5.3.0-1010.11
linux-image-5.3.0-29-generic - 5.3.0-29.31
linux-image-5.3.0-29-generic-lpae - 5.3.0-29.31
linux-image-5.3.0-29-lowlatency - 5.3.0-29.31
linux-image-5.3.0-29-snapdragon - 5.3.0-29.31
linux-image-aws - 5.3.0.1010.12
linux-image-generic - 5.3.0.29.33
linux-image-generic-lpae - 5.3.0.29.33
linux-image-lowlatency - 5.3.0.29.33
linux-image-virtual - 5.3.0.29.33
To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.

USN-4255-2: Linux kernel (HWE) vulnerabilities
28 January 2020
linux-hwe, linux-aws-hwe vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 16.04 LTS
Summary
Several security issues were fixed in the Linux kernel.
Software Description
o linux-aws-hwe - Linux kernel for Amazon Web Services (AWS-HWE) systems
o linux-hwe - Linux hardware enablement (HWE) kernel
Details
USN-4255-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This
update provides the corresponding updates for the Linux Hardware Enablement
(HWE) kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS.
It was discovered that the Linux kernel did not properly clear data structures
on context switches for certain Intel graphics processors. A local attacker
could use this to expose sensitive information. (CVE-2019-14615)
It was discovered that a race condition can lead to a use-after-free while
destroying GEM contexts in the i915 driver for the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2020-7053)
Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 16.04 LTS
linux-image-4.15.0-1058-aws - 4.15.0-1058.60~16.04.1
linux-image-4.15.0-76-generic - 4.15.0-76.86~16.04.1
linux-image-4.15.0-76-generic-lpae - 4.15.0-76.86~16.04.1
linux-image-4.15.0-76-lowlatency - 4.15.0-76.86~16.04.1
linux-image-aws-hwe - 4.15.0.1058.58
linux-image-generic-hwe-16.04 - 4.15.0.76.96
linux-image-generic-lpae-hwe-16.04 - 4.15.0.76.96
linux-image-lowlatency-hwe-16.04 - 4.15.0.76.96
linux-image-oem - 4.15.0.76.96
linux-image-virtual-hwe-16.04 - 4.15.0.76.96
To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
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.
