The vulnerability is caused due to the incorrect initialisation of the proto_ops structure for certain protocols (e.g. PF_APPLETALK, PF_IPX, PF_IRDA, PF_X25, PF_AX25 families, PF_BLUETOOTH, PF_IUCV, PF_INET6 (with IPPROTO_SCTP), PF_PPPOX, and PF_ISDN), which can be exploited to cause a NULL pointer dereference when triggering the "sock_sendpage()" function for an incorrectly initialised socket. SOLUTION: Fixed in version 2.6.31-rc6.
