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-2026-97487 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-2026-97487/ (Markdown: https://insights.sbomify.com/CVE-2026-97487/index.md)","id":"CVE-2026-97487","markdown":"https://insights.sbomify.com/CVE-2026-97487/index.md","name":"CVE-2026-97487","record":{"aliases":["AZL-103541","BELL-CVE-2026-97487","DEBIAN-CVE-2026-97487","GHSA-w9g3-rpmc-68j2","UBUNTU-CVE-2026-97487"],"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":"high_privilege","summary":"A local attacker with mount privileges can cause a kernel crash in the JFS filesystem by triggering a block size handling error.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\njfs: handle set_blocksize failures\n\njfs uses buffer_heads, which don't handle block size \u003e PAGE_SIZE well.\nWithout this, mounting we will hit the\n\n        BUG_ON(offset \u003e= folio_size(folio));\n\nin folio_set_bh on the first __bread_gfp call.","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":"jfs: handle set_blocksize failures","id":"CVE-2026-97487","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"qnx4: handle set_blocksize failures","id":"CVE-2026-97488"},"packages":[],"prev":{"headline":"hpfs: handle set_blocksize failures","id":"CVE-2026-97486"},"products":["Linux"],"published":"2026-09-24","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":"2026-10-03","vendors":["Linux"]},"summary":"A local attacker with mount privileges can cause a kernel crash in the JFS filesystem by triggering a block size handling error.","url":"https://insights.sbomify.com/CVE-2026-97487/"}
