Background
The xprtrdma package is a component of the Linux Kernel ecosystem. It provides support for Remote Procedure Call (RPC) over RDMA (Remote Direct Memory Access) transport. RDMA allows for high-performance data transfers between remote systems. The rpcrdma_ep_create function is responsible for creating an RDMA endpoint for RPC communication. However, there are pointer dereference issues in error cases of this function, which can lead to potential security vulnerabilities.
Vulnerability Detail
The vulnerability in the xprtrdma package arises from pointer dereferences in error cases of the rpcrdma_ep_create function. These pointer dereferences can result in memory corruption or crashes, potentially leading to privilege escalation or denial of service attacks. The vulnerability has been assigned the ID GSD-2022-1000408. It is important to note that the impact and attack plausibility of this vulnerability have not yet been proven.
