CVE-2022-50426

5.5 · MEDIUM
Published Oct 1, 2025 linux EPSS 0.15% (5th pctl)

Overview

CVE-2022-50426 is a medium-severity vulnerability affecting linux linux_kernel. It was published on October 1, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: imx_dsp_rproc: Add mutex protection for workqueue

The workqueue may execute late even after remoteproc is stopped or

stopping, some resources (rpmsg device and endpoint) have been

released in rproc_stop_subdevices(), then rproc_vq_interrupt()

accessing these resources will cause kennel dump.

Call trace:

virtqueue_add_split+0x1ac/0x560

virtqueue_add_inbuf+0x4c/0x60

rpmsg_recv_done+0x15c/0x294

vring_interrupt+0x6c/0xa4

rproc_vq_interrupt+0x30/0x50

imx_dsp_rproc_vq_work+0x24/0x40 [imx_dsp_rproc]

process_one_work+0x1d0/0x354

worker_thread+0x13c/0x470

kthread+0x154/0x160

ret_from_fork+0x10/0x20

Add mutex protection in imx_dsp_rproc_vq_work(), if the state is

not running, then just skip calling rproc_vq_interrupt().

Also the flush workqueue operation can't be added in rproc stop

for the same reason. The call sequence is

rproc_shutdown

-> rproc_stop

->rproc_stop_subdevices

->rproc->ops->stop(

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
