Background

The rds package is a part of the Linux Kernel ecosystem. It provides the implementation for the Reliable Datagram Sockets (RDS) protocol, which allows for reliable and high-performance communication between processes on different machines. The vulnerability in question is a memory leak that occurs in the __rds_conn_create() function.

Vulnerability Detail

The vulnerability is introduced in version v5.13 of the Linux Kernel by commit aced3ce57cd37b5ca332bcacd370d01f5a8c5371 and is fixed in version v5.15.11 by commit 68014890e4382ff9192e1357be39b7d0455665fa. When the __rds_conn_create() function is called, it leaks memory, which can lead to resource exhaustion and potential denial-of-service attacks. The impact and attack plausibility of this vulnerability have not been proven yet.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.15.11 or later. This can be done by pulling the latest changes from the official Linux Kernel repository: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/
