CVE-2026-43165 Details
Description
In the Linux kernel, the following vulnerability has been resolved: hwmon: (nct7363) Fix a resource leak in nct7363_present_pwm_fanin When calling of_parse_phandle_with_args(), the caller is responsible to call of_node_put() to release the reference of device node. In nct7363_present_pwm_fanin, it does not release the reference, causing a resource leak.
A resource leak vulnerability has been identified in the Linux kernel's NCT7363 hardware monitoring driver. The issue arises in the 'nct7363_present_pwm_fanin' function, where a reference to a device node is not properly released after being parsed. This oversight creates a resource leak, as the function fails to call 'of_node_put()' to relinquish the node reference, leaving it dangling.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit fixing this issue is available in the Linux kernel stable tree.
