Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ASoC: fsl_xcvr: Revert fix missing lock in fsl_xcvr_mode_put()<br />
<br />
This reverts commit f51424872760 ("ASoC: fsl_xcvr: fix missing lock in fsl_xcvr_mode_put()").<br />
<br />
The original patch attempted to acquire the card->controls_rwsem lock in<br />
fsl_xcvr_mode_put(). However, this function is called from the upper ALSA<br />
core function snd_ctl_elem_write(), which already holds the write lock on<br />
controls_rwsem for the whole put operation. So there is no need to simply<br />
hold the lock for fsl_xcvr_activate_ctl() again.<br />
<br />
Acquiring the read lock while holding the write lock in the same thread<br />
results in a deadlock and a hung task, as reported by Alexander Stein.
