This vulnerability affects all versions of SNMP — Versions 1, 2c, and 3. An attacker could exploit this vulnerability by sending a malformed SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly. The attacker must have the SNMPv1 or v2c read-only or read-write community string or valid SNMPv3 user credentials on the affected device.","severity":"HIGH","kev":false,"epss":{"score":0.00345,"percentile":0.27164,"score_date":"2026-08-09","updated_at":"2026-08-10T05:36:57Z"},"cvss_score":7.7,"cvss_source":"NVD","cwe":"CWE-772","published_at":"2026-08-05T17:16:46Z","modified_at":"2026-08-06T15:44:56Z"},"freshness":{"last_source_refreshed_at":"2026-08-10T05:36:57Z","latest_source_refresh_at":"2026-08-10T05:36:57Z","oldest_source_refresh_at":"2026-08-10T03:00:02Z","all_sources_fresh":true,"sources":[{"source":"cisco_advisories","label":"Cisco advisories","last_success_at":"2026-08-10T03:00:02Z","stale":false},{"source":"cisco_csaf","label":"Cisco CSAF","last_success_at":"2026-08-10T05:34:32Z","stale":false},{"source":"nvd_cves","label":"NVD CVEs","last_success_at":"2026-08-10T05:36:54Z","stale":false},{"source":"cisa_kev","label":"CISA KEV","last_success_at":"2026-08-10T05:36:54Z","stale":false},{"source":"first_epss","label":"EPSS","last_success_at":"2026-08-10T05:36:57Z","stale":false}]},"summary":{"advisory_count":2,"visible_product_count":2,"public_evidence_count":2,"kev":false,"cvss_score":7.7},"advisories":[{"id":"cisco-sa-iosxe-snmp-dos-ZAqNm4MD","slug":"cisco-sa-iosxe-snmp-dos-zaqnm4md","title":"Cisco IOS XE Software SNMP Denial of Service Vulnerability","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-snmp-dos-ZAqNm4MD"},{"id":"cisco-sa-notice-L4XfJg8S","slug":"cisco-sa-notice-l4xfjg8s","title":"Cisco Advance Notification for Publication of August 5, 2026, Security Advisories","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-notice-L4XfJg8S"}],"public_evidence":[{"product":{"name":"Cisco IOS XE Software","slug":"cisco-ios-xe-software","vendor":"Cisco"},"advisory":{"id":"cisco-sa-iosxe-snmp-dos-ZAqNm4MD","slug":"cisco-sa-iosxe-snmp-dos-zaqnm4md","title":"Cisco IOS XE Software SNMP Denial of Service Vulnerability","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-snmp-dos-ZAqNm4MD"},"evidence_type":"structured_affected","evidence_label":{"scope":"CSAF product evidence","label":"product_status known affected"},"evidence_source":"Cisco CSAF","source":"Cisco CSAF","source_document_fetched_at":"2026-08-06T04:00:20Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"16.10.1a;
