Descriptions

Kernel/VM/MemoryManager.cpp in SerenityOS before 2019-12-30 does not reject syscalls with pointers into the kernel-only virtual address space, which allows local users to gain privileges by overwriting a return address that was found on the kernel stack.

El archivo Kernel/VM/MemoryManager.cpp en SerenityOS antes de 30-12-2019 no rechaza las llamadas al sistema con punteros en el espacio de direcciones virtuales solo del kernel, lo que permite a usuarios locales alcanzar privilegios sobrescribiendo una dirección de retorno que fue encontrada en la pila del kernel.
