However, this function is called from the upper ALSA core function snd_ctl_elem_write(), which already holds the write lock on controls_rwsem for the whole put operation. So there is no need to simply hold the lock for fsl_xcvr_activate_ctl() again.</p> <p>Acquiring the read lock while holding the write lock in the same thread results in a deadlock and a hung task, as reported by Alexander Stein.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ASoC: fsl_xcvr: Revert fix missing lock in fsl_xcvr_mode_put()</p> <p>This reverts commit f51424872760 (&#34;ASoC: fsl_xcvr: fix missing lock in fsl_xcvr_mode_put()&#34;).</p> <p>The original patch attempted to acquire the card-&gt;controls_rwsem lock in fsl_xcvr_mode_put().
