An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76879 in the wild and no public exploit code.\n\nAffected product: Wireshark Wireshark. 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-2026-76879/ (Markdown: https://insights.sbomify.com/CVE-2026-76879/index.md)","id":"CVE-2026-76879","markdown":"https://insights.sbomify.com/CVE-2026-76879/index.md","name":"CVE-2026-76879","record":{"aliases":["AZL-96809","DEBIAN-CVE-2026-76879","GHSA-wjf3-82r2-8vvm","MINI-x6gc-5gqg-c484","UBUNTU-CVE-2026-76879"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Network protocol analyzer","requires_auth":"none","summary":"A stack-based buffer overflow in the C12.22 dissector allows attackers to cause a denial of service via crafted packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"wireshark","vendor":"wireshark"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"C12.22 protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service","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":"Stack-based Buffer Overflow in Wireshark","id":"CVE-2026-76879","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wireshark:wireshark","products":["wireshark:wireshark"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Out-of-bounds Write in Wireshark","id":"CVE-2026-76880"},"packages":[],"prev":{"headline":"Missing authorization in Aodh","id":"CVE-2026-76878"},"products":["Wireshark"],"published":"2026-08-19","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-0444","kev_date_added":null,"published":"2011-01-12"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-2994","kev_date_added":null,"published":"2010-08-13"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-2995","kev_date_added":null,"published":"2010-08-13"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-1266","kev_date_added":null,"published":"2009-04-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-1210","kev_date_added":null,"published":"2009-04-01"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-3146","kev_date_added":null,"published":"2008-09-02"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-6112","kev_date_added":null,"published":"2007-11-23"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["Wireshark Foundation"]},"summary":"A stack-based buffer overflow in the C12.22 dissector allows attackers to cause a denial of service via crafted packets.","url":"https://insights.sbomify.com/CVE-2026-76879/"}
