Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: accel/rocket: initialize job domain before cleanup paths rocket_ioctl_submit_job() releases rjob through rocket_job_put() on allocation error paths. rocket_job_cleanup() unconditionally calls rocket_iommu_domain_put(job->domain), but job->domain is assigned only after task copying and BO lookups. A failure before that assignment can therefore clean up a job with a NULL domain pointer. Take the per-file domain reference before the first error path can release rjob. Also clear rjob->tasks after freeing it in rocket_copy_tasks(), so the common cleanup path cannot free the task array again after a task-copy error.
