CVE-2026-43165

Description

A flaw was found in the Linux kernel's hwmon subsystem, specifically in the nct7363 driver. This resource leak occurs in the nct7363_present_pwm_fanin function because a device node reference is not properly released after being acquired. An attacker with local access could potentially exploit this to cause resource exhaustion, leading to a Denial of Service (DoS) on the system.
