========================================================================== Ubuntu Security Notice USN-4253-1 January 28, 2020
linux, linux-aws vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.10
Summary:
The Linux kernel could be made to expose sensitive information.
Software Description: - linux: Linux kernel - 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
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.
