Ubuntu 14.04 LTS : Linux kernel regressions (USN-3741-3)

medium Nessus Plugin ID 112017

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3741-3 advisory.

 USN-3741-1 introduced mitigations in the Linux kernel for Ubuntu 14.04 LTS to address L1 Terminal Fault (L1TF) vulnerabilities (CVE-2018-3620, CVE-2018-3646). Unfortunately, the update introduced regressions that caused kernel panics when booting in some environments as well as preventing Java applications from starting. This update fixes the problems.

 We apologize for the inconvenience.



Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
