Details

In the Linux kernel, the following vulnerability has been resolved: drivers: staging: rtl8723bs: Fix deadlock in rtwsurveydoneeventcallback() There is a deadlock in rtwsurveydoneeventcallback(), which is shown below: (Thread 1) | (Thread 2) | settimer() rtwsurveydoneeventcallback()| modtimer() spinlockbh() //(1) | (wait a time) ... | rtwscantimeouthandler() deltimersync() | spinlockbh() //(2) (wait timer to stop) | ... We hold pmlmepriv->lock in position (1) of thread 1 and use deltimersync() to wait timer to stop, but timer handler also need pmlmepriv->lock in position (2) of thread 2. As a result, rtwsurveydoneeventcallback() will block forever. This patch extracts deltimersync() from the protection of spinlockbh(), which could let timer handler to obtain the needed lock. What`s more, we change spinlockbh() in rtwscantimeouthandler() to spinlockirq(). Otherwise, spinlock_bh() will also cause deadlock() in timer handler.
