Description Dhananjay Arunesh 2019-06-07 08:07:17 UTC
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).
