he Linux kernel could be made to expose sensitive information.

USN-4253-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.10.
This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 19.10 for Ubuntu
18.04 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.
