  "description": "In the Linux kernel, the following vulnerability has been resolved:  drivers: usb: host: Fix deadlock in oxu_bus_suspend()  There is a deadlock in oxu_bus_suspend(), which is shown below:     (Thread 1)              |      (Thread 2)                            | timer_action() oxu_bus_suspend()          |  mod_timer()  spin_lock_irq() //(1)     |  (wait a time)  ...                       | oxu_watchdog()  del_timer_sync()          |  spin_lock_irq() //(2)  (wait timer to stop)      |  ...  We hold oxu-\u003Elock in position (1) of thread 1, and use del_timer_sync() to wait timer to stop, but timer handler also need oxu-\u003Elock in position (2) of thread 2. As a result, oxu_bus_suspend() will block forever.  This patch extracts del_timer_sync() from the protection of spin_lock_irq(), which could let timer handler to obtain the needed lock.",
