Attackers who have physical laptop access can exhaust the main battery to reset the BIOS configuration, and then achieve direct access to the hard drive by booting a live USB OS without disassembling the laptop. NOTE: the vendor has apparently indicated that this is \"normal\" and use of the same battery for the BIOS and the overall system is a \"new design.\" However, the vendor apparently plans to \"improve\" this an unspecified later time","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":6.8},"cwes":[],"references":["https://blog.modpr0.be/2019/10/18/asus-rog-bios-reset-on-lost-battery-power/","https://blog.modpr0.be/2019/10/18/asus-rog-bios-reset-on-lost-battery-power/"],"products":["asus:rog_zephyrus_m_gm501gs_firmware"],"source":"nvd","synced_at":"2026-10-19T20:59:10.855360465+00:00"},"epss":{"cve":"CVE-2019-18216","score":0.00376,"percentile":0.31609,"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).
