Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel (GKE) regression (USN-6152-1)

info Nessus Plugin ID 177080

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6152-1 advisory.

It was discovered that NFS client's access cache implementation in the Linux kernel caused a severe NFS performance degradation in certain conditions. This updated makes the NFS file-access stale cache behavior to be optional.

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.
