  "description": "In the Linux kernel, the following vulnerability has been resolved:  drivers: staging: rtl8192eu: Fix deadlock in rtw_joinbss_event_prehandle  There is a deadlock in rtw_joinbss_event_prehandle(), which is shown below:     (Thread 1)                |      (Thread 2)                              | _set_timer() rtw_joinbss_event_prehandle()|  mod_timer()  spin_lock_bh() //(1)        |  (wait a time)  ...                         | rtw_join_timeout_handler()                              |  _rtw_join_timeout_handler()  del_timer_sync()            |   spin_lock_bh() //(2)  (wait timer to stop)        |   ...  We hold pmlmepriv-\u003Elock in position (1) of thread 1 and use del_timer_sync() to wait timer to stop, but timer handler also need pmlmepriv-\u003Elock in position (2) of thread 2. As a result, rtw_joinbss_event_prehandle() will block forever.  This patch extracts del_timer_sync() from the protection of spin_lock_bh(), which could let timer handler to obtain the needed lock. What\u0060s more, we change spin_lock_bh() to spin_lock_irq() in _rtw_join_timeout_handler() in order to prevent deadlock.",
