CVE-2011-1093: n/a vulnerability

CVE-2011-1093: The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP)...

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.

Security readout for executives and security teams

CVE-2011-1093 is a Linux kernel denial-of-service flaw in DCCP handling. A remote attacker could crash an affected kernel if DCCP is reachable. The issue affects Linux kernels before 2.6.38; business urgency depends on whether legacy Linux systems still expose or load DCCP. Likely exposure is legacy Linux systems running kernels before 2.6.38 with DCCP enabled or reachable. The bundle does not identify affected distributions beyond public vendor references, so confirm exposure through asset and package inventory. Treat as a legacy infrastructure risk. Prioritize internet-facing or untrusted-network Linux systems first, especially unsupported appliances or embedded systems where kernel patch status may be unclear. Mitigation focus: Update affected Linux kernels using vendor-supported packages or a release containing the upstream fix.; Review Red Hat, kernel, and product vendor advisories for platform-specific remediation guidance.; Retire or isolate unsupported legacy Linux systems where kernel updates are not available..
