The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. Note: BIP39 secrets are not displayed by default on this device. The side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2019-11-02 17:15:00","updated_at":"2021-07-21 11:39:00"},"problem_types":["CWE-203"],"metrics":[],"references":[{"url":"https://blog.inhq.net/posts/oled-side-channel-status-summary/","name":"https://blog.inhq.net/posts/oled-side-channel-status-summary/","refsource":"MISC","tags":["Exploit","Third Party Advisory"],"title":"OLED Side Channel - Summary October 2019 | invd blog","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2019-18673","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-18673","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2019","cve_id":"18673","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"h","cpe4":"shiftcrypto","cpe5":"bitbox02","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2019","cve_id":"18673","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"h","cpe4":"shiftcrypto","cpe5":"bitbox02","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2019-18673","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"On SHIFT BitBox02 devices, a side channel for the row-based OLED display was found.
