Kernel NULL Pointer Dereference while starting rootless container with podman + crun

While doing some tests with podman and user container (through toolbox), I encountered a kernel bug that seems related to apparmor.

For some context, the system is Archlinux with kernel 6.17.8-arch1-1, apparmor 5.0.0.alpha2.r17.g455d50e (i.e commit 455d50ec from master branch), and all profiles moved to abi 5.0. On one of the test VM used for apparmor.d

The bug happens when starting a rootless container using toolbox with podman and crun as runtime (it works fine with runc). After a toolbox create arch to create the container, toolbox enter arch will fail and fail any subsequent attempt to start a namespace on the system.

The general profiles (test) architecture is as-follow (but only the last part matters here):

toolbox -(px)-> podman -(px)-> conmon -(px)-> crun

The crun profile is literally profile crun flags=(attach_disconnected,mediate_deleted) { all, }. Similar tests but with transition to a namespace gave exactly the same result.

The full kernel logs (with also apparmor debug)
