I was also able to reproduce using the above reproducer[1] [1] - cat /sys/module/apparmor/parameters/audit
I think the problem here is that files in apparmor shouldn't be writable while apparmor is disable. (-rw-------) If I do : # chmod 400 /sys/module/apparmor/parameters/audit (-r--------) then # cat /sys/module/apparmor/parameters/audit doesn't crash and displays : "Invalid argument", just like upstream kernel does. - Eric -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626984 Title: kernel BUG at /build/linux-lts-xenial-_hWfOZ/linux-lts- xenial-4.4.0/security/apparmor/include/context.h:69!
