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)"}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/xe/xe_vm.c"], "versions": [{"version": "9e978741488261e117bb50e5dfcf8e4080990958", "lessThan": "279339aa8bdcf9db40094cf2bcbd495c53dbe817", "status": "affected", "versionType": "git"}, {"version": "9e978741488261e117bb50e5dfcf8e4080990958", "lessThan": "9ac92736030f3395d970c300eaeb59ac258a0c3e", "status": "affected", "versionType": "git"}, {"version": "9e978741488261e117bb50e5dfcf8e4080990958", "lessThan": "d2c6800ad1802bed72a6de1416536737f114f1d6", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/xe/xe_vm.c"], "versions": [{"version": "6.18", "status": "affected"}, {"version": "0", "lessThan": "6.18", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc5", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "7.2-rc5"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/279339aa8bdcf9db40094cf2bcbd495c53dbe817"}, {"url": "https://git.kernel.org/stable/c/9ac92736030f3395d970c300eaeb59ac258a0c3e"}, {"url": "https://git.kernel.org/stable/c/d2c6800ad1802bed72a6de1416536737f114f1d6"}], "title": "drm/xe/vm: Fix SVM leak on resv obj alloc failure in xe_vm_create()", "x_generator": {"engine": "bippy-1.2.0"}}}}
