I see you've sent 44 reports like this recently[1], but only have reproducers for 4 of them[2]. Without reproducers these reports aren't very helpful. There are hundreds like them (many with reproducers) already at: https://syzkaller.appspot.com/upstream Please only send these kind of reports if you have a fix for them (preferred) or a reproducer for an actual problem. This has been mentioned a few times already[3][4]; have you seen these replies? -Kees [1] https://lore.kernel.org/all/?q=f%3Axli399%40 [2] https://lore.kernel.org/all/?q=f%3Axli399%40+%22The+reproducer%22 [3] https://lore.kernel.org/netdev/CANn89iK6rq0XWO5-R5CzA5YAv2ygaTA==EVh+O74VHGDBNqUoA@mail.gmail.com/ [4] https://lore.kernel.org/all/20240829011805.92574-1-kuniyu@amazon.com/ -- Kees Cook
