Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix "kernel NULL pointer dereference" error When rxe_queue_init in the function rxe_qp_init_req fails, both qp->req.task.func and qp->req.task.arg are not initialized. Because of creation of qp fails, the function rxe_create_qp will call rxe_qp_do_cleanup to handle allocated resource. Before calling __rxe_do_task, both qp->req.task.func and qp->req.task.arg should be checked.

Executive Summary

This vulnerability is a kernel NULL pointer dereference error in the Linux kernel's RDMA rxe driver. Specifically, when the function rxe_qp_init_req fails during queue pair (qp) initialization, certain task function pointers (qp->req.task.func and qp->req.task.arg) are not initialized. Later, when cleanup is performed by rxe_create_qp calling rxe_qp_do_cleanup, these uninitialized pointers are used without proper checks, leading to a NULL pointer dereference.

Impact Analysis

The impact of this vulnerability is that it can cause a kernel NULL pointer dereference, which typically results in a kernel crash or system instability. This can lead to denial of service on affected systems running the vulnerable Linux kernel with the RDMA rxe driver.
