Описание
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.
Отчет
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 not 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.
