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-2026-98518 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-2026-98518/ (Markdown: https://insights.sbomify.com/CVE-2026-98518/index.md)","id":"CVE-2026-98518","markdown":"https://insights.sbomify.com/CVE-2026-98518/index.md","name":"CVE-2026-98518","record":{"aliases":["DEBIAN-CVE-2026-98518","GHSA-84w9-cx8r-cxrf","UBUNTU-CVE-2026-98518"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory corruption vulnerability in the Linux kernel's nouveau driver allows local attackers to execute arbitrary code or escalate privileges due to incorrect VRAM buffer sizing.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/nouveau/dmem: pin VRAM for the whole registered range\n\nCommit c32287471077 (\"gpu/drm/nouveau: enable THP support for GPU memory\nmigration\") grew the device-private region that\nnouveau_dmem_chunk_alloc() registers from DMEM_CHUNK_SIZE to\nDMEM_CHUNK_SIZE * NR_CHUNKS, but left the VRAM buffer object backing that\nregion at DMEM_CHUNK_SIZE.\n\nnouveau_dmem_page_addr() returns chunk-\u003ebo-\u003eoffset plus the page's offset\nwithin the registered region, so every page past the first chunk resolves\nto VRAM outside the buffer object.\n\nSize the buffer object to the region it backs.","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/nouveau/dmem: pin VRAM for the whole registered range","id":"CVE-2026-98518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"drm/amdgpu: Fix runtime PM leak in amdgpu_debugfs_test_ib_show()","id":"CVE-2026-98519"},"packages":[],"prev":{"headline":"drm/nouveau/uvmm: fix UAF in nouveau_uvmm_sm when BO is in TTM_PL_SYSTEM","id":"CVE-2026-98517"},"products":["Linux"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-24","vendors":["Linux"]},"summary":"A memory corruption vulnerability in the Linux kernel's nouveau driver allows local attackers to execute arbitrary code or escalate privileges due to incorrect VRAM buffer sizing.","url":"https://insights.sbomify.com/CVE-2026-98518/"}
