Descriptions

The ip_cmsg_recv_checksum function in net/ipv4/ip_sockglue.c in the Linux kernel before 4.10.1 has incorrect expectations about skb data layout, which allows local users to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted system calls, as demonstrated by use of the MSG_MORE flag in conjunction with loopback UDP transmission.

La función ip_cmsg_recv_checksum en net/ipv4/ip_sockglue.c en el kernel de Linux en versiones anteriores a 4.10.1 tiene expectativas incorrectas sobre la disposición de datos skb, lo que permite a usuarios locales provocar una denegación de servicio (sobre lectura de búfer) o la posibilidad de tener otro impacto no especificado a través de llamadas al sistema manipulado, como lo demuestra el uso de indicadores MSG_MORE en conjunción con la trasmisión del bucle de retorno UDP.
