## Overview

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

drm/rockchip: analogix_dp: fix unchecked bound endpoint name length

rockchip_dp_drm_encoder_enable() uses sprintf() to format a device tree
path into a 32-byte stack buffer. Device tree paths are not limited to
this size, so a sufficiently long path can overflow the buffer.

Use snprintf() with the destination size to truncate the generated name
and keep the writes within bounds.

## Remediation

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