Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix unsafe drain work queue code If create_qp does not fully succeed it is possible for qp cleanup code to attempt to drain the send or recv work queues before the queues have been created causing a seg fault. This patch checks to see if the queues exist before attempting to drain them.

Executive Summary

This vulnerability occurs in the Linux kernel's RDMA/rxe component where, if the creation of a queue pair (create_qp) does not fully succeed, the cleanup code may try to drain the send or receive work queues before they have been created. This can cause a segmentation fault (crash). The fix involves adding a check to ensure the queues exist before attempting to drain them.

Impact Analysis

The vulnerability can cause a segmentation fault in the Linux kernel, potentially leading to system instability or crashes when the RDMA/rxe component's queue pairs fail to be created properly and the cleanup code runs. This could disrupt services relying on RDMA functionality.
