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-2026-21996 in the wild and no public exploit code.\n\nAffected product: Oracle 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-2026-21996/ (Markdown: https://insights.sbomify.com/CVE-2026-21996/index.md)","id":"CVE-2026-21996","markdown":"https://insights.sbomify.com/CVE-2026-21996/index.md","name":"CVE-2026-21996","record":{"aliases":["DEBIAN-CVE-2026-21996","GHSA-w2v2-5qjc-q2jw","UBUNTU-CVE-2026-21996"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Oracle Linux dtrace","requires_auth":"low_privilege","summary":"An unprivileged attacker can crash the dtrace process by providing a malicious ELF binary, causing a denial of service on Oracle Linux systems.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"linux","vendor":"oracle"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"An unprivileged attacker can reliably trigger a crash of the dtrace process with a malicious ELF binary due to an integer Divide-by-Zero in Pbuild_file_symtab()","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":"Denial of service in Oracle Linux","id":"CVE-2026-21996","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"oracle:linux","products":["oracle:linux"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Oracle Life Sciences Empirica Signal","id":"CVE-2026-21997"},"packages":[],"prev":{"headline":"Auth bypass in Oracle Edge Cloud Infrastructure Designer and Visualisation Toolkit","id":"CVE-2026-21994"},"products":["Oracle Linux"],"published":"2026-05-01","related":[{"cvss_score":7.8,"headline":"Red Hat Automatic Bug Reporting Tool Privilege Escalation","id":"CVE-2015-5287","kev_date_added":"2026-08-26","published":"2015-12-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-5408","kev_date_added":null,"published":"2016-08-10"},{"cvss_score":8.1,"headline":"Memory corruption in n/a","id":"CVE-2016-1714","kev_date_added":null,"published":"2016-04-07"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-3812","kev_date_added":null,"published":"2015-05-26"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2015-2328","kev_date_added":null,"published":"2015-12-02"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2015-8385","kev_date_added":null,"published":"2015-12-02"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2015-8388","kev_date_added":null,"published":"2015-12-02"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-01","vendors":["Oracle Corporation"]},"summary":"An unprivileged attacker can crash the dtrace process by providing a malicious ELF binary, causing a denial of service on Oracle Linux systems.","url":"https://insights.sbomify.com/CVE-2026-21996/"}
