## Overview

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

configfs: fix lockless traversals of ->s_children

Having the parent directory locked protects entries from removal
by another thread, but it does *not* protect cursors from being
moved around by lseek() - or freed, for that matter.

## Remediation

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