Calendar Grey January 25, 2024
Dist Ubuntu Esm H88
Critical kernel fixes for multiple security issues in Ubuntu 16.04 and 18.04 addressing denial of service vulnerabilities.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems

- linux-kvm: Linux kernel for cloud environments

- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems

- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems

- linux-hwe: Linux hardware enablement (HWE) kernel

- linux-oracle: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the ASUS HID driver in the Linux kernel did not

properly handle device removal, leading to a use-after-free vulnerability.

A local attacker with physical access could plug in a specially crafted USB

device to cause a denial of service (system crash). (CVE-2023-1079)

Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Kopf, and Oleksii

Oleksenko discovered that some AMD processors could leak stale data from

   linux-image-virtual             4.15.0.221.205

Ubuntu 16.04 LTS (Available with Ubuntu Pro):
   linux-image-4.15.0-1127-oracle  4.15.0-1127.138~16.04.1
   linux-image-4.15.0-1158-gcp     4.15.0-1158.175~16.04.1
   linux-image-4.15.0-1164-aws     4.15.0-1164.177~16.04.1
   linux-image-4.15.0-221-generic  4.15.0-221.232~16.04.1
   linux-image-4.15.0-221-lowlatency  4.15.0-221.232~16.04.1
   linux-image-aws-hwe             4.15.0.1164.147
   linux-image-gcp                 4.15.0.1158.148
   linux-image-generic-hwe-16.04   4.15.0.221.5
   linux-image-gke                 4.15.0.1158.148
   linux-image-lowlatency-hwe-16.04  4.15.0.221.5
   linux-image-oem                 4.15.0.221.5
   linux-image-oracle              4.15.0.1127.108
   linux-image-virtual-hwe-16.04   4.15.0.221.5

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.
