Ubuntu Security Notice USN-4627-1
Posted Nov 11, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4627-1 - Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running Average Power Limit driver in the Linux kernel did not properly restrict access to power data. A local attacker could possibly use this to expose sensitive information.

linux, linux-gcp, linux-gcp-4.15, linux-gcp-5.4, linux-gke-4.15,
linux-gke-5.3, linux-hwe, linux-hwe-5.4, linux-oem, linux-oem-osp1,
linux-oracle, linux-oracle-5.4 vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 ESM
- Ubuntu 12.04 ESM

Summary:

The system could be made to expose sensitive information.

Software Description:
- linux: Linux kernel
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gke-4.15: Linux kernel for Google Container Engine (GKE) systems
- linux-gke-5.3: Linux kernel for Google Container Engine (GKE) systems
- linux-hwe: Linux hardware enablement (HWE) kernel
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-oem: Linux kernel for OEM systems
- linux-oem-osp1: Linux kernel for OEM systems
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM

Details:

Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine
Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running
Average Power Limit (RAPL) driver in the Linux kernel did not properly
restrict access to power data. A local attacker could possibly use this to
expose sensitive information.

Update instructions:

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.
