A resource leak vulnerability has been identified in the Linux kernel's NFC (Near Field Communication) subsystem, specifically within the netlink interface. The issue arises because the function nfc_get_device() acquires a reference to a device but fails to release it when no longer needed, potentially leading to resource leaks. This vulnerability affects several versions of the Linux kernel.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability. The patches are included in the official Linux kernel Git repository.
