[alsa-devel] Reminder: 1 open syzbot bug in sound subsystem
[This email was generated by a script. Let me know if you have any suggestions to make it better, or if you want it re-generated with the latest status.]
Of the currently open syzbot reports against the upstream kernel, I've manually marked 1 of them as possibly being a bug in the sound subsystem.
If you believe this bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at https://goo.gl/tpsmEJ#status
If you believe I misattributed this bug to the sound subsystem, please let me know, and if possible forward the report to the correct people or mailing list.
Here is the bug:

This one doesn't look like a bug that is directly related with the sound stuff. Although it was triggered from a sound ioctl, UAF is seen rather in a notifier chain of other component.
thanks,

Okay, I'm not sure what to do with this bug though. I'll mark it as unknown subsystem for now.
By the way, thanks for addressing all the syzbot reports in the sound subsystem!
