CVE-2025-38419

Technical Description

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

remoteproc: core: Cleanup acquired resources when rproc_handle_resources() fails in rproc_attach()

When rproc->state = RPROC_DETACHED and rproc_attach() is used

to attach to the remote processor, if rproc_handle_resources()

returns a failure, the resources allocated by imx_rproc_prepare()

should be released, otherwise the following memory leak will occur.

Since almost the same thing is done in imx_rproc_prepare() and

rproc_resource_cleanup(), Function rproc_resource_cleanup() is able

to deal with empty lists so it is better to fix the "goto" statements

in rproc_attach(). replace the "unprepare_device" goto statement with

"clean_up_resources" and get rid of the "unprepare_device" label.

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.
