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-2026-98506 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-2026-98506/ (Markdown: https://insights.sbomify.com/CVE-2026-98506/index.md)","id":"CVE-2026-98506","markdown":"https://insights.sbomify.com/CVE-2026-98506/index.md","name":"CVE-2026-98506","record":{"aliases":["AZL-109293","BELL-CVE-2026-98506","DEBIAN-CVE-2026-98506","GHSA-rgpg-w634-4pfv","UBUNTU-CVE-2026-98506"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"A local attacker can corrupt the hugetlb free list by dissolving gigantic pages without runtime support, potentially causing a system crash or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/hugetlb: do not dissolve gigantic pages without runtime support\n\ndissolve_free_hugetlb_folio() doesn't check\nhstate_is_gigantic_no_runtime(h) though remove_hugetlb_folio()/\nupdate_and_free_hugetlb_folio() silently bail for such folios, so it frees\na still-listed folio and, on vmemmap restore failure, the\nadd_hugetlb_folio() rollback corrupts the free list.","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":"mm/hugetlb: do not dissolve gigantic pages without runtime support","id":"CVE-2026-98506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"mm/rmap: fix missing barrier between anon_vma init and vma-\u003eanon_vma publish","id":"CVE-2026-98507"},"packages":[],"prev":{"headline":"mm/damon/vaddr: avoid hw-driven pte updates during damon_hugetlb_mkold()","id":"CVE-2026-98505"},"products":["Linux"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A local attacker can corrupt the hugetlb free list by dissolving gigantic pages without runtime support, potentially causing a system crash or code execution.","url":"https://insights.sbomify.com/CVE-2026-98506/"}
