Mô tả CVE
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.
