Description

A flaw was found in the Linux kernel's Universal Flash Storage (UFS) driver. During device error recovery, the driver pauses all command queues, which inadvertently prevents internal recovery commands from being dispatched. This condition can result in an unrecoverable circular wait deadlock, leading to a Denial of Service (DoS) through a system hang.
