linux, linux-aws vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
The Linux kernel could be made to expose sensitive information.
Software Description
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.
