Descriptions

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).

Se descubrió un problema en dlpar_parse_cc_property en arch / powerpc / platform / pseries / dlpar.c en el kernel de Linux hasta la versión 5.1.6. Hay un kstrdup sin marcar de prop-> name, que podría permitir que un atacante provoque una denegación de servicio (desreferencia de puntero NULL y bloqueo del sistema).

A flaw was found in the way Linux kernel's Dynamic Logical Partitioning (DLPAR) functionality on PowerPC systems handled low memory conditions on device discovery. An attacker who can change the LPAR configuration and incur low memory conditions at the same time could use this flaw to crash the system.
