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.

Security readout for executives and security teams

This is an old Linux kernel availability flaw in the RDS subsystem. A local user could trigger a kernel crash on systems running Linux before 2.6.38, causing service interruption. It is not described as remote code execution, and the provided sources do not show active exploitation. Exposure is most likely on legacy Linux systems running kernels before 2.6.38 where RDS is present and local user access exists. Modern maintained distributions are unlikely to be exposed unless running very old or custom kernels without the referenced fix. Treat this as a legacy platform hygiene and availability issue. It is not KEV-listed and requires local access, but unpatched old kernels can still create outage risk on business-critical systems. Mitigation focus: Update to a kernel or vendor backport containing the referenced RDS fix.; Confirm vendor advisories for supported distribution-specific remediation guidance.; Prioritize legacy or custom kernels where local users can access the system..
