    Unfortantely, some of the reports are making it to the lkml.

    200KB each! Due to attached .config files. I believe you should not be
    spamming lkml in the first place. If you insist on sending to lkml and
    list admins are okay with that, please gzip the config file.

    Looks like the same bug I sent out a fix for yesterday.

    #syz fix: capabilities: fix buffer overread on very short xattr
