Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel regression (USN-4660-2)

info Nessus Plugin ID 144112

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4660-2 advisory.

 USN-4660-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem.



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.
