Linux Kernel Multiple Vulnerabilities

Release Date: 10 Sep 2021 1162 Views

RISK: Medium Risk

TYPE: Operating Systems - Linux

TYPE: Linux

Multiple vulnerabilities were identified in Linux Kernel, a remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, remote code execution, sensitive information disclosure, data manipulation and security restriction bypass on the targeted system.


Impact

  • Denial of Service
  • Remote Code Execution
  • Security Restriction Bypass
  • Information Disclosure
  • Data Manipulation

System / Technologies affected

  • Ubuntu 14.04 ESM
  • Ubuntu 16.04 ESM
  • Ubuntu 18.04 LTS
  • Ubuntu 20.04 LTS
  • Ubuntu 21.04

Solutions

Before installation of the software, please visit the vendor web-site for more details.

 

The problem can be corrected by updating your system to the following package versions:

  • Ubuntu 14.04 ESM
  • Ubuntu 16.04 ESM
  • Ubuntu 18.04 LTS
  • Ubuntu 20.04 LTS
  • Ubuntu 21.04

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.
