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-2009-2406 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2009-2406/ (Markdown: https://insights.sbomify.com/CVE-2009-2406/index.md)","id":"CVE-2009-2406","markdown":"https://insights.sbomify.com/CVE-2009-2406/index.md","name":"CVE-2009-2406","record":{"aliases":["GHSA-86jh-hvhg-x8w9"],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["denial_of_service","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can cause a system crash or potentially gain privileges via a crafted eCryptfs file due to a stack-based buffer overflow in the Linux kernel.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"kernel","vendor":"linux"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":6.9,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Stack-based buffer overflow in the parse_tag_11_packet function in fs/ecryptfs/keystore.c in the eCryptfs subsystem in the Linux kernel before 2.6.30.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving a crafted eCryptfs file, related to not ensuring that the key signature length in a Tag 11 packet is compatible with the key signature buffer size.","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":"Memory corruption in n/a","id":"CVE-2009-2406","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2009"},"n_packages":0,"n_references":27,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-2407"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2009-2405"},"products":["n/a"],"published":"2009-07-31","related":[{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2009-2844","kev_date_added":null,"published":"2009-08-18"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2009-1389","kev_date_added":null,"published":"2009-06-16"},{"cvss_score":7.2,"headline":"Null dereference in n/a","id":"CVE-2009-2767","kev_date_added":null,"published":"2009-08-14"},{"cvss_score":6.8,"headline":"Denial of service in n/a","id":"CVE-2010-0309","kev_date_added":null,"published":"2010-02-12"},{"cvss_score":4.9,"headline":"Information disclosure in n/a","id":"CVE-2009-2847","kev_date_added":null,"published":"2009-08-18"},{"cvss_score":4.6,"headline":"Use after free in n/a","id":"CVE-2009-3624","kev_date_added":null,"published":"2009-11-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Local attackers can cause a system crash or potentially gain privileges via a crafted eCryptfs file due to a stack-based buffer overflow in the Linux kernel.","url":"https://insights.sbomify.com/CVE-2009-2406/"}
