## Overview

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

eth: fbnic: Fix payload page pool error cleanup

The payload page pool pointer contains an error pointer when its
allocation fails. The cleanup path passes that error pointer to
page_pool_destroy() instead of destroying the header page pool. This
can dereference the error pointer and leave the header page pool
allocated.

Destroy the header page pool instead.

- `Linux >= 8a11010fdd9615e8dbb2f5d562ab88caa8a9516a < 8e0b235bd918d06f54ba8fddd2c3ddc36ca59c15`
