## Overview

In the Linux kernel, the following vulnerability has been resolved:

page_pool: always add GFP_NOWARN for ATOMIC allocations

Driver authors often forget to add GFP_NOWARN for page allocation
from the datapath. This is annoying to users as OOMs are a fact
of life, and we pretty much expect network Rx to hit page allocation
failures during OOM. Make page pool add GFP_NOWARN for ATOMIC allocations
by default.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
