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If you believe this bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at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:
Title: KASAN: use-after-free Read in wake_up_if_idle Last occurred: 131 days ago Reported: 267 days ago Branches: Mainline and others Dashboard link: https://syzkaller.appspot.com/bug?id=b1e300cd7b124fc83dd4199d4d1df26310111b0... Original thread: https://lkml.kernel.org/lkml/00000000000066ab7105795f245e@google.com/T/#u
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,
