## Overview

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

vdpa/mlx5: fix wrong list iterated in add_direct_chain error path

In add_direct_chain(), newly allocated direct MR entries are added to
the local list 'tmp', which is spliced into mr->head only on success.
On the error path, the cleanup loop was incorrectly iterating over
mr->head instead of tmp.

Fix by iterating over 'tmp' in the err_alloc cleanup path.

## Remediation

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