It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-68298 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-68298/ (Markdown: https://insights.sbomify.com/CVE-2026-68298/index.md)","id":"CVE-2026-68298","markdown":"https://insights.sbomify.com/CVE-2026-68298/index.md","name":"CVE-2026-68298","record":{"aliases":["BELL-CVE-2026-68298","DEBIAN-CVE-2026-68298","GHSA-w7rf-7rxm-hr7v","UBUNTU-CVE-2026-68298"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel's Xe GPU driver can lead to resource exhaustion and denial of service when VM creation fails.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/vm: Fix SVM leak on resv obj alloc failure in xe_vm_create()\n\nCommit 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.

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-\u003esize = 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)","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"drm/xe/vm: Fix SVM leak on resv obj alloc failure in xe_vm_create()","id":"CVE-2026-68298","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets","id":"CVE-2026-68299"},"packages":[],"prev":{"headline":"tipc: fix u16 MTU truncation in media and bearer MTU validation","id":"CVE-2026-68297"},"products":["Linux"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's Xe GPU driver can lead to resource exhaustion and denial of service when VM creation fails.","url":"https://insights.sbomify.com/CVE-2026-68298/"}
