CVE-2025-38418

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

remoteproc: core: Release rproc->clean_table after rproc_attach() fails

When rproc->state = RPROC_DETACHED is attached to remote processor through rproc_attach(), if rproc_handle_resources() returns failure, then the clean table should be released, otherwise the following memory leak will occur.
