Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.0.2. This issue affects the function rxe_qp_init_req. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-50671 since 12/09/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 302405 (EulerOS 2.0 SP10 : kernel (EulerOS-SA-2026-1313)), which helps to determine the existence of the flaw in a target environment.
