| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrivers: staging: rtl8192bs: Fix deadlock in rtw_joinbss_event_prehandle()\n\nThere is a deadlock in rtw_joinbss_event_prehandle(), which is shown\nbelow:\n\n (Thread 1) | (Thread 2)\n | _set_timer()\nrtw_joinbss_event_prehandle()| mod_timer()\n spin_lock_bh() //(1) | (wait a time)\n ... | _rtw_join_timeout_handler()\n del_timer_sync() | spin_lock_bh() //(2)\n (wait timer to stop) | ...\n\nWe hold pmlmepriv->lock in position (1) of thread 1 and\nuse del_timer_sync() to wait timer to stop, but timer handler\nalso need pmlmepriv->lock in position (2) of thread 2.\nAs a result, rtw_joinbss_event_prehandle() will block forever.\n\nThis patch extracts del_timer_sync() from the protection of\nspin_lock_bh(), which could let timer handler to obtain\nthe needed lock. What`s more, we change spin_lock_bh() to\nspin_lock_irq() in _rtw_join_timeout_handler() in order to\nprevent deadlock." |
