## Overview

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

soc: qcom: qmi_encdec: Restrict string length in decode

The QMI TLV value for strings in a lot of qmi element info structures
account for null terminated strings with MAX_LEN + 1. If a string is
actually MAX_LEN + 1 length, this will cause an out of bounds access
when the NULL character is appended in decoding.

## Remediation

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