  "details" : [ "The Reliable Datagram Sockets (RDS) subsystem in the Linux kernel before 2.6.38 does not properly handle congestion map updates, which allows local users to cause a denial of service (BUG_ON and system crash) via vectors involving (1) a loopback (aka loop) transmit operation or (2) an InfiniBand (aka ib) transmit operation." ],
  "statement" : "The Linux kernel as shipped with Red Hat Enterprise Linux 4 and Red Hat Enterprise MRG did not include support for the RDS Protocol, and therefore are\nnot affected by this issue. The Linux kernel as shipped with Red Hat Enterprise Linux 5 and 6 are not affected as they did not backport upstream commit 2e7b3b99 and 77dd550e that introduced this issue.",
