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-2026-98685 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-2026-98685/ (Markdown: https://insights.sbomify.com/CVE-2026-98685/index.md)","id":"CVE-2026-98685","markdown":"https://insights.sbomify.com/CVE-2026-98685/index.md","name":"CVE-2026-98685","record":{"aliases":["AZL-108978","BELL-CVE-2026-98685","DEBIAN-CVE-2026-98685","GHSA-r85p-j355-crhr","UBUNTU-CVE-2026-98685"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"low_privilege","summary":"A local attacker can read stale pagecache data past the end of file when extending files via SMB clone operations in the Linux kernel.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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\nsmb: client: discard post-EOF pagecache when extending a file via clone range\n\ncifs_remap_file_range() discarded the pagecache only for the folios\noverlapping the destination region, so when a clone extends the file the\nfolio straddling the old EOF - which may hold data dirtied past EOF\nthrough an mmap - was never dropped and became visible as file content\nonce the file was extended.\n\nStart the discard at the smaller of fstart and the old EOF.  i_size is\nstill old here, so nothing past the old EOF is flushed to the server.","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":"smb: client: discard post-EOF pagecache when extending a file via clone range","id":"CVE-2026-98685","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"smb: client: discard post-EOF pagecache when extending a file via zero range","id":"CVE-2026-98686"},"packages":[],"prev":{"headline":"smb: client: flush and commit data before querying allocated ranges","id":"CVE-2026-98684"},"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 read stale pagecache data past the end of file when extending files via SMB clone operations in the Linux kernel.","url":"https://insights.sbomify.com/CVE-2026-98685/"}
