Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.38

Description The issue is related to the Reliable Datagram Sockets (RDS) subsystem in the Linux kernel, which does not properly handle congestion map updates. This can be exploited by local users to cause a denial of service, resulting in a system crash. The exploitation vectors involve either a loopback transmit operation or an InfiniBand transmit operation.

Recommendations For Linux kernel versions prior to 2.6.38, update to version 2.6.38 or later to resolve the issue.
