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-2026-68240 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-2026-68240/ (Markdown: https://insights.sbomify.com/CVE-2026-68240/index.md)","id":"CVE-2026-68240","markdown":"https://insights.sbomify.com/CVE-2026-68240/index.md","name":"CVE-2026-68240","record":{"aliases":["BELL-CVE-2026-68240","DEBIAN-CVE-2026-68240","GHSA-hg58-rvxm-hmcv","UBUNTU-CVE-2026-68240"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel GPU driver","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel GPU SVM driver allows attackers to exhaust system resources by triggering error paths during page mapping.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/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/gpusvm: publish dpagemap early to avoid device mapping leak on error\n\ndrm_gpusvm_get_pages() only stored the local dpagemap into\nsvm_pages-\u003edpagemap on the success path.
