It is not reported as exploited. Patch Radar priority: High.", "title": "amd/amdkfd: enhance kfd process check in switch partition", "description": "In the Linux kernel, the following vulnerability has been resolved: amd/amdkfd: enhance kfd process check in switch partition current switch partition only check if kfd_processes_table is empty. kfd_prcesses_table entry is deleted in kfd_process_notifier_release, but kfd_process tear down is in kfd_process_wq_release. consider two processes: Process A (workqueue) -\u003E kfd_process_wq_release -\u003E Access kfd_node member Process B switch partition -\u003E amdgpu_xcp_pre_partition_switch -\u003E amdgpu_amdkfd_device_fini_sw -\u003E kfd_node tear down. Process A and B may trigger a race as shown in dmesg log. This patch is to resolve the race by adding an atomic kfd_process counter kfd_processes_count, it increment as create kfd process, decrement as finish kfd_process_wq_release. v2: Put kfd_processes_count per kfd_dev, move decrement to kfd_process_destroy_pdds and bug fix.
