Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel regression (USN-5267-2)

info Nessus Plugin ID 157458

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5267-2 advisory.

 USN-5267-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression that caused the kernel to freeze when accessing CIFS shares in some situations.

 This update fixes the problem.

 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.
