Reliable Datagram Sockets (RDS) is a high-performance, low-latency, reliable, connectionless protocol for delivering datagrams. It is developed by Oracle Corporation.
It was included in the Linux kernel 2.6.30 which was released on 9th of June, 2009. The code was contributed by the OpenFabrics Alliance (OFA).[1]
On October 19, 2010, VSR announced CVE-2010-3904, a vulnerability within the Linux 2.6.30 kernel which could result in a local privilege escalation via the kernel's implementation of RDS.[2] This was subsequently fixed in Linux 2.6.36.[3]
On May 8, 2019, CVE-2019-11815 was published, regarding a race condition in the Linux RDS implementation that could lead to a use-after-free bug and possible arbitrary code execution.[4] The bug has been fixed in Linux 5.0.8.
