A vulnerability was found in Linux Kernel, where a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client.
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1851481]
This was fixed for Fedora with the 5.1 kernel rebases.
The affected functionality not used by rhel* (means not inside kernel).
Checked that non-relevant for rhel*.
Closing as NOTABUG.
