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-2026-48684 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-48684/ (Markdown: https://insights.sbomify.com/CVE-2026-48684/index.md)","id":"CVE-2026-48684","markdown":"https://insights.sbomify.com/CVE-2026-48684/index.md","name":"CVE-2026-48684","record":{"aliases":["DEBIAN-CVE-2026-48684","GHSA-6jf7-3j4w-4v3m","UBUNTU-CVE-2026-48684"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Network monitoring software","requires_auth":"none","summary":"An out-of-bounds read in FastNetMon's NetFlow v9 parser allows attackers to cause denial of service or disclose memory contents via crafted UDP packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fastnetmon","vendor":"pavel-odintsov"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"FastNetMon Community Edition through 1.2.9 contains an out-of-bounds read in the NetFlow v9 options template parser. In process_netflow_v9_options_template() (src/netflow_plugin/netflow_v9_collector.cpp), the scope parsing loop (lines 224-229) iterates until scopes_offset reaches the attacker-controlled option_scope_length value, reading netflow9_template_flowset_record_t structures at each step. No bounds check validates that (zone_address + scopes_offset + sizeof(record)) stays within the flowset. The same issue affects the options field loop (lines 241-257) with option_length. Furthermore, option_scope_length is not validated to be a multiple of sizeof(netflow9_template_flowset_record_t), potentially causing misaligned reads. An attacker can trigger reads past the end of the UDP packet buffer.","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":"Memory corruption in n/a","id":"CVE-2026-48684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2026-48685"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2026-48683"},"products":["n/a"],"published":"2026-05-26","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2026-48686","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2026-48689","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2026-48687","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Missing authorization in n/a","id":"CVE-2026-48692","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2026-48694","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2026-48695","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2026-48688","kev_date_added":null,"published":"2026-05-26"}],"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":"2026-05-26","vendors":["n/a"]},"summary":"An out-of-bounds read in FastNetMon's NetFlow v9 parser allows attackers to cause denial of service or disclose memory contents via crafted UDP packets.","url":"https://insights.sbomify.com/CVE-2026-48684/"}
