It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2009-1337 exists.\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-2009-1337/ (Markdown: https://insights.sbomify.com/CVE-2009-1337/index.md)","id":"CVE-2009-1337","markdown":"https://insights.sbomify.com/CVE-2009-1337/index.md","name":"CVE-2009-1337","record":{"aliases":["GHSA-w3gg-x9j7-v653"],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by exploiting a flaw in the Linux kernel's exit signal handling to send arbitrary signals to setuid applications.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2009-04-08","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-04-08","kind":"exploitdb","ref":"8369","stars":null,"title":"Linux Kernel \u003c 2.6.29 - 'exit_notify()' Local Privilege Escalation"}],"tier":"weaponised"},"has_fix":true,"headline":"Privilege escalation in n/a","id":"CVE-2009-1337","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"privilege_escalation","year":"2009"},"n_packages":0,"n_references":49,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2009-1338"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-1336"},"products":["n/a"],"published":"2009-04-22","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Local attackers can escalate privileges by exploiting a flaw in the Linux kernel's exit signal handling to send arbitrary signals to setuid applications.","url":"https://insights.sbomify.com/CVE-2009-1337/"}
