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-2026-102021 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-2026-102021/ (Markdown: https://insights.sbomify.com/CVE-2026-102021/index.md)","id":"CVE-2026-102021","markdown":"https://insights.sbomify.com/CVE-2026-102021/index.md","name":"CVE-2026-102021","record":{"aliases":["GHSA-w7mj-v6m2-38qq"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Juniper Junos OS","requires_auth":"none","summary":"An adjacent attacker can crash the routing daemon via a crafted RSVP packet when MPLS-TE error processing is enabled, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/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 routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent network attacker to cause a denial of service via a crafted RSVP packet when MPLS-TE RSVP processing is enabled.
