## Overview

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

mptcp: fix bad accounting in __mptcp_subflow_push_pending()

If __subflow_push_pending() errors out we should avoid updating the
copied byte counters, to avoid mismatch push call later on.

## Remediation

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