Description OSIDB Bzimport 2025-10-01 12:05:21 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ALSA: ac97: fix possible memory leak in snd_ac97_dev_register()

If device_register() fails in snd_ac97_dev_register(), it should
call put_device() to give up reference, or the name allocated in
dev_set_name() is leaked.
