Уязвимость компонента arch/powerpc/mm/mmu_context_book3s64.c ядра операционной системы Linux, позволяющая нарушителю получить доступ к содержимому памяти или вызвать повреждение памяти других процессов в системе

An issue was discovered in get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup_const of node_info->vdev_port.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).

arch/powerpc/mm/mmu_context_book3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected.
