Hi, Please excuse us for forgetting to attach the following information to the previous email. This bug seems to be related to a bug previously found by syzbot (https://syzkaller.appspot.com/bug?extid=7902cd7684bc35306224) and fixed (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c791730f2554a9ebb8f18df9368dc27d4ebc38c2). The fixing commit is present in the kernel version that we analyzed, yet the reproducer is still able to trigger the bug. I hope this information helps in further debugging this issue! Best, Marius
