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 9 June 2009. The code was contributed by the OpenFabrics Alliance (OFA).
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. This was subsequently fixed in Linux 2.6.36.
On May 8, "2019," CVE-2019-11815 was published, regarding race condition in the Linux RDS implementation that could lead to a use-after-free bug and possible arbitrary code execution. The bug has been fixed in Linux 5.0.8.
