Ubuntu 20.04 LTS : Linux kernel (Azure) regression (USN-5092-3)

info Nessus Plugin ID 154205

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5092-3 advisory.

 USN-5092-2 fixed vulnerabilities in Linux 5.11-based kernels. Unfortunately, for Linux kernels intended for use within Microsoft Azure environments, that update introduced a regression that could cause the kernel to fail to boot in large Azure instance types. 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.
