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-2026-101940 in the wild and no public exploit code.\n\nAffected product: Juniper Networks Junos OS. 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-2026-101940/ (Markdown: https://insights.sbomify.com/CVE-2026-101940/index.md)","id":"CVE-2026-101940","markdown":"https://insights.sbomify.com/CVE-2026-101940/index.md","name":"CVE-2026-101940","record":{"aliases":["GHSA-mm2r-8hqh-vh2p"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"An unauthenticated BGP peer can crash the routing daemon via a crafted UPDATE when ISO-VPN egress protection is enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:A/V:C/RE:M","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A NULL Pointer Dereference vulnerability in the rpd routing daemon of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated configured BGP peer to cause a denial of service via a BGP UPDATE when ISO-VPN and egress-protection configuration is enabled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Junos OS and Junos OS Evolved: An attacker causes a routing-daemon crash when BGP ISO-VPN egress protection is enabled","id":"CVE-2026-101940","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in Junos OS","id":"CVE-2026-101941"},"packages":[],"prev":{"headline":"Null dereference in Junos OS","id":"CVE-2026-101939"},"products":["Junos OS","Junos OS Evolved"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-18","vendors":["Juniper Networks"]},"summary":"An unauthenticated BGP peer can crash the routing daemon via a crafted UPDATE when ISO-VPN egress protection is enabled.","url":"https://insights.sbomify.com/CVE-2026-101940/"}
