In the Linux kernel, the following vulnerability has been resolved:
remoteproc: core: Release rproc->cleantable after rprocattach() fails
When rproc->state = RPROCDETACHED is attached to remote processor through rprocattach(), if rprochandleresources() returns failure, then the clean table should be released, otherwise the following memory leak will occur.
