FKIE_CVE-2022-50671
Vulnerability from fkie_nvd - Published: 2025-12-09 16:17 - Updated: 2026-10-15 22:17
Severity
Summary
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 MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
