leds: uleds: Fix potential buffer overread
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: leds: uleds: Fix potential buffer overread The name string supplied by userspace is not guaranteed to be null-terminated, so using strchr() on it might result in a buffer overread. The same thing will happen when said string is used by the LED class device. Fix this by using strnchr() instead and explicitly check that the name string is properly null-terminated.

Solution
Apply kernel patch to prevent buffer overread by ensuring null termination.
- Ensure user-supplied strings are null-terminated.
- Use strnchr() for safer string handling.
- Update the Linux kernel to the patched version.
