If the protocol has been compiled using default settings, this will only grant the attacker access to allocated but unused memory. However, if it was configured using non-default settings, there is the possibility that exploiting this vulnerability could lead to system crashes and remote code execution.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-787"],"references":["https://github.com/Sub-IoT/Sub-IoT-Stack/security/advisories/GHSA-ggxh-88wc-c4fg","https://www.cisa.gov/news-events/ics-advisories/icsa-23-047-13","https://github.com/Sub-IoT/Sub-IoT-Stack/security/advisories/GHSA-ggxh-88wc-c4fg","https://www.cisa.gov/news-events/ics-advisories/icsa-23-047-13"],"products":["dash7-alliance:dash7_alliance_protcol"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-0847","score":0.00817,"percentile":0.57135,"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).
