It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-6867 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-2026-6867/ (Markdown: https://insights.sbomify.com/CVE-2026-6867/index.md)","id":"CVE-2026-6867","markdown":"https://insights.sbomify.com/CVE-2026-6867/index.md","name":"CVE-2026-6867","record":{"aliases":["AZL-85178","DEBIAN-CVE-2026-6867","GHSA-r6mg-v3f6-8v7r","UBUNTU-CVE-2026-6867"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Network protocol analyzer","requires_auth":"none","summary":"A crash in the SMB2 dissector allows attackers to cause a denial of service in Wireshark.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"wireshark","vendor":"wireshark"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1325","name":"Improperly Controlled Sequential Memory Allocation"}],"description":"SMB2 protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 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":"Improperly Controlled Sequential Memory Allocation in Wireshark","id":"CVE-2026-6867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wireshark:wireshark","products":["wireshark:wireshark"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Stack-based Buffer Overflow in Wireshark","id":"CVE-2026-6868"},"packages":[],"prev":{"headline":"Initialization of a Resource with an Insecure Default vulnerability on EcoStruxure™ Panel Server","id":"CVE-2026-6866"},"products":["Wireshark"],"published":"2026-04-30","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-30","vendors":["Wireshark Foundation"]},"summary":"A crash in the SMB2 dissector allows attackers to cause a denial of service in Wireshark.","url":"https://insights.sbomify.com/CVE-2026-6867/"}
