The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel before 2.6.38 does not properly handle packets for a CLOSED endpoint, which allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet.

CVE-2011-1093 [HIGH] CWE-672 kernel: dccp: fix oops on Reset after close
kernel: dccp: fix oops on Reset after close
The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel before 2.6.38 does not properly handle packets for a CLOSED endpoint, which allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet.
Statement: This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not include support for the DCCP protocol. Future updates in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG may address this flaw.
Mitigation: For users that do not run applications that use DCCP, you can prevent the dccp
