Reliable Datagram Sockets

Reliable Datagram Sockets 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.
On October 19, 2010, VSR announced, 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, 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]. The bug has been fixed in Linux 5.0.8.
