An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).

This is a potential null pointer dereference that looks like it can
only be invoked by root or the hypervisor. Probably no security impact.
