This vulnerability is due to insufficient validation of certain parameters within 802.11 frames. An attacker could exploit this vulnerability by sending a wireless 802.11 association request frame with crafted parameters to an affected device. A successful exploit could allow the attacker to cause an unexpected reload of an affected device, resulting in a DoS condition.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-125","CWE-126"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-assoc-dos-D2SunWK2","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-assoc-dos-D2SunWK2"],"products":["cisco:business_150ax_firmware","cisco:business_151axm_firmware","cisco:catalyst_9105ax_firmware","cisco:catalyst_9105axi_firmware","cisco:catalyst_9105axw_firmware","cisco:catalyst_9105i_firmware","cisco:catalyst_9105w_firmware","cisco:catalyst_9115_firmware","cisco:catalyst_9115ax_firmware","cisco:catalyst_9115axe_firmware","cisco:catalyst_9115axi_firmware","cisco:catalyst_9117_firmware","cisco:catalyst_9117ax_firmware","cisco:catalyst_9117axi_firmware","cisco:catalyst_9120_firmware","cisco:catalyst_9120ax_firmware","cisco:catalyst_9120axe_firmware","cisco:catalyst_9120axi_firmware","cisco:catalyst_9120axp_firmware","cisco:catalyst_9124_firmware","cisco:catalyst_9124ax_firmware","cisco:catalyst_9124axd_firmware","cisco:catalyst_9124axi_firmware","cisco:catalyst_9130_firmware","cisco:catalyst_9130ax_firmware","cisco:catalyst_9130axe_firmware","cisco:catalyst_9130axi_firmware","cisco:catalyst_9136_firmware","cisco:catalyst_9162_firmware","cisco:catalyst_9164_firmware","cisco:catalyst_9166_firmware"],"source":"nvd","synced_at":"2026-10-19T21:37:48.383111019+00:00"},"epss":{"cve":"CVE-2023-20112","score":0.00303,"percentile":0.23072,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
