In the Linux kernel, the following vulnerability has been resolved:

ALSA: pcm: oss: Fix data race at accessing runtime.oss.trigger

Currently the runtime.oss.trigger field may be accessed concurrently

without protection, which may lead to the data race. And, in this

case, it may lead to more severe problem because it's a bit field; as

writing the data, it may overwrite other bit fields as well, which

confuses the operation completely, as spotted by fuzzing.

Fix it by covering runtime.oss.trigger bit fled also with the existing

params_lock mutex in both snd_pcm_oss_get_trigger() and

snd_pcm_oss_poll(). (NVD)
