Descriptions
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.
La memoria de pila InfiniBand (también conocida como IB) en el kernel de Linux en versiones anteriores a 4.5.3 confía incorrectamente en llamadas al sistema de escritura, lo que permite a usuarios locales provocar una denegación de servicio (operación de escritura en la memoria del kernel) o posiblemente tener otro impacto no especificado a través de una interfaz uAPI.
A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.
