Description

A flaw was found in the Linux kernel, specifically within the Near Field Communication (NFC) NCI subsystem. A circular locking dependency can occur when the `nci_close_device()` function attempts to flush work queues while holding a lock that can be re-acquired by a work queue function. This improper handling of locks can lead to a system hang, resulting in a denial of service (DoS).
