Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a deadlock in the ALSA component of the Linux kernel, specifically in the
snd card disconnect() function. This occurs when a process waits for power up at snd power ref and wait() in snd ctl info() or read/write() inside card->controls rwsem, and the system gets disconnected meanwhile, causing the driver to try to delete a kctl via snd ctl remove*(). The fix involves waking up sleepers before processing the driver disconnect callbacks but right after setting the card->shutdown flag. This change allows the code to flow again without deadlocks.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
