9e9787414882 (\"drm/xe/userptr: replace xe_hmm with gpusvm\") made\nxe_svm_init() unconditional in xe_vm_create() and extended it to also\ninitialize a \"simple\" gpusvm state for non-fault-mode VMs. The matching\nxe_svm_fini() call in xe_vm_close_and_put() was updated to run\nunconditionally, but the error unwind path in xe_vm_create() was not.\n\nOn the drm_gpuvm_resv_object_alloc() failure path, xe_svm_init() has\nalready succeeded but xe_svm_fini() is only called when\nXE_VM_FLAG_FAULT_MODE is set. For non-fault-mode VMs this leaves\nvm->svm.gpusvm partially initialized and leaks the resources allocated\nby drm_gpusvm_init().\n\nFor fault-mode VMs, xe_svm_init() additionally acquires the pagemap\nowner via drm_pagemap_acquire_owner() and the pagemaps via\nxe_svm_get_pagemaps(). Those resources are released by xe_svm_close(),\nnot xe_svm_fini(). On the same error path, xe_svm_close() is not\ncalled either, so fault-mode VMs leak the pagemap owner and pagemaps.\n\nFix both leaks:\n\n- Call xe_svm_fini() unconditionally on the err_svm_fini path, matching\n the unconditional xe_svm_init() call. Move the vm->size = 0\n assignment out of the conditional so the xe_vm_is_closed() assert in\n xe_svm_fini() (and xe_svm_close()) holds for both modes.\n\n- Call xe_svm_close() for fault-mode VMs before xe_svm_fini(), matching\n the ordering used in xe_vm_close_and_put().\n\n(cherry picked from commit ca2a3587d577ba764e0fe628fb676244fc33ddd4)", "title": "Vulnerability description" }, { "category": "other", "text": "TuxCare has assessed that this vulnerability does not impact any currently supported TuxCare products.
