An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-89147 exists.\n\nAffected product: Net-SNMP. 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-2026-89147/ (Markdown: https://insights.sbomify.com/CVE-2026-89147/index.md)","id":"CVE-2026-89147","markdown":"https://insights.sbomify.com/CVE-2026-89147/index.md","name":"CVE-2026-89147","record":{"aliases":["AZL-101742","DEBIAN-CVE-2026-89147","ECHO-c070-0905-6b62","GHSA-hv9m-8m5p-82j6","ROOT-OS-ALPINE-323-CVE-2026-89147","UBUNTU-CVE-2026-89147"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SNMP server software","requires_auth":"none","summary":"Unauthenticated remote attackers can cause a denial of service in Net-SNMP by blocking the SMUX listener, suspending all SNMP processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","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:N","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-1088","name":"Synchronous Access of Remote Resource without Timeout"}],"description":"Net-SNMP through 5.9.5.2 contains a denial of service vulnerability in the SMUX module where smux_accept() performs an unauthenticated blocking read without timeout on newly accepted connections.
