[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



[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 3 of them as possibly being bugs in the hid subsystem.  I've listed these
reports below, sorted by an algorithm that tries to list first the reports most
likely to be still valid, important, and actionable.

Of these 3 bugs, 2 were seen in mainline in the last week.

If you believe a bug is no longer valid, please close the syzbot report by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 a bug to the hid subsystem, please let me know,
and if possible forward the report to the correct people or mailing list.

Here are the bugs:
