NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump-devel package and not the kernel-kdump-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
