Description Prasad J Pandit 2013-03-07 18:28:33 UTC
Linux kernels built with Datagram Congestion Control Protocol(DCCP),
are vulnerable to a NULL pointer dereference flaw. This occurs while accessing socket options of dccp_sock objects via ccid_hc_rx_getsockopt & ccid_hc_tx_getsockopt routines.

A user/program could use this flaw to crash the kernel, resulting in DoS.
