## Overview

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

gpiolib: fix invalid pointer access in debugfs

If the memory allocation in gpiolib_seq_start() fails, the s->private
field remains uninitialized and is later dereferenced without checking
in gpiolib_seq_stop(). Initialize s->private to NULL before calling
kzalloc() and check it before dereferencing it.

## Remediation

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