Descriptions
Integer overflow in the uvm_map_isavail function in uvm/uvm_map.c in OpenBSD 5.9 allows local users to cause a denial of service (kernel panic) via a crafted mmap call, which triggers the new mapping to overlap with an existing mapping.
Desbordamiento de entero en la función uvm_map_isavail en uvm/uvm_map.c en OpenBSD 5.9 permite a usuarios locales provocar una denegación de servicio (pánico en el kernel) a través de una llamada mmap manipulada, lo que desencadena el nuevo mapeo para superponerse con un mapeo existente.
