[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 6 of them as possibly being bugs in the "net/dccp" 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. If you believe a bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at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 "net/dccp" subsystem, please let me know, and if possible forward the report to the correct people or mailing list. Here are the bugs: -------------------------------------------------------------------------------- Title: KASAN: use-after-free Read in ccid2_hc_tx_packet_recv Last occurred: 26 days ago Reported: 477 days ago Branches: Mainline and others Dashboard link: https://syzkaller.appspot.com/bug?id=31f032fe94df7aca6ce5d45455f6acefa26515e4 Original thread: https://lkml.kernel.org/lkml/0000000000003872fd0568da185f@xxxxxxxxxx/T/#u This bug has a C reproducer.
