Affected devices insufficiently control continuous mapping of direct memory access (DMA) requests. This could allow local attackers with administrative privileges to cause a denial of service situation on the host. A physical power cycle is required to get the system working again.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","score":4.4},"cwes":["CWE-400"],"references":["https://cert-portal.siemens.com/productcert/pdf/ssa-784849.pdf","https://cert-portal.siemens.com/productcert/pdf/ssa-784849.pdf"],"products":["siemens:simatic_cp_1604_firmware","siemens:simatic_cp_1616_firmware","siemens:simatic_cp_1623_firmware","siemens:simatic_cp_1626_firmware","siemens:simatic_cp_1628_firmware"],"source":"nvd","synced_at":"2026-10-19T21:39:34.467980132+00:00"},"epss":{"cve":"CVE-2023-37195","score":0.00174,"percentile":0.06821,"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).
