CVE-2025-38419 Affecting python3-perf package, versions *

Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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.
