Description SMASH SMASH 2024-02-06 11:44:04 UTC 
A race condition was found in the Linux kernel's sound/hda  device driver in snd_hdac_regmap_sync() function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or denial of service issue.

Closing as WONT FIX since code path won't reach until the driver gets probed, hence a suggested race can't happen at all
