CVE-2026-72241

leds: uleds: Fix potential buffer overread

State: Published
Severity: Not scored
Published: Aug 15, 2026
Updated: Aug 17, 2026
Reserved: Aug 9, 2026

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.

Scores

The record has no CVSS score.
