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).[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.
