(CVE-2018-12179).\n\nInsufficient memory write check in SMM service for EDK II may allow an\nauthenticated user to potentially enable escalation of privilege, information\ndisclosure and/or denial of service via local access. (CVE-2018-12182).\n\nStack overflow in DxeCore for EDK II may allow an unauthenticated user to\npotentially enable escalation of privilege, information disclosure and/or\ndenial of service via local access. (CVE-2018-12183).\n\nBuffer overflow in system firmware for EDK II may allow unauthenticated user\nto potentially enable escalation of privilege and/or denial of service via\nnetwork access. (CVE-2019-0160).\n\nStack overflow in XHCI for EDK II may allow an unauthenticated user to\npotentially enable denial of service via local access. (CVE-2019-0161).\n\nImproper authentication in EDK II may allow a privileged user to potentially\nenable information disclosure via network access. (CVE-2019-14553).\n\nInsufficient control flow management in BIOS firmware for 8th, 9th, 10th\nGeneration Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 & 5000 Series\nProcessors may allow an authenticated user to potentially enable denial of\nservice via adjacent access. (CVE-2019-14558).\n\nUncontrolled resource consumption in EDK II may allow an unauthenticated user\nto potentially enable denial of service via network access. (CVE-2019-14559).\n\nInteger truncation in EDK II may allow an authenticated user to potentially\nenable escalation of privilege via local access. (CVE-2019-14563).\n\nLogic issue in DxeImageVerificationHandler() for EDK II may allow an\nauthenticated user to potentially enable escalation of privilege via local\naccess. (CVE-2019-14575).\n\nEDK II incorrectly parsed signed PKCS #7 data. An attacker could use this\nissue to cause EDK II to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2019-14584).\n\nUse after free vulnerability in EDK II may allow an authenticated user to\npotentially enable escalation of privilege, information disclosure and/or\ndenial of service via adjacent access. (CVE-2019-14586).\n\nLogic issue EDK II may allow an unauthenticated user to potentially enable\ndenial of service via adjacent access. (CVE-2019-14587).\n\nInteger overflow in DxeImageVerificationHandler() EDK II may allow an\nauthenticated user to potentially enable denial of service via local access.\n(CVE-2019-14562).","dates":{"published":"2021-01-17T16:07:01.000Z","modified":"2026-04-16T04:42:41.889Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"edk2","name":"edk2","label":"edk2","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/edk2","purlType":"rpm","versions":[{"text":"< 20201127stable-1.mga7","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 20201127stable-1.mga7","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2021-0035.html","label":"advisories.mageia.org/MGASA-2021-0035.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=25939","label":"bugs.mageia.org/show_bug.cgi?id=25939","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/TQYVZRFEXSN3KS43AVH4D7QX553EZQYP/","label":"lists.fedoraproject.org/archives/…","hostname":"lists.fedoraproject.org","tags":["WEB"]},{"url":"https://access.redhat.com/errata/RHSA-2020:1712","label":"access.redhat.com/errata/RHSA-2020:1712","hostname":"access.redhat.com","tags":["WEB"]},{"url":"https://usn.ubuntu.com/4349-1/","label":"usn.ubuntu.com/4349-1/","hostname":"usn.ubuntu.com","tags":["WEB"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/A23OH3MXQU7WURSP4PC66EXMG6INYFH6/","label":"lists.fedoraproject.org/archives/…","hostname":"lists.fedoraproject.org","tags":["WEB"]},{"url":"https://ubuntu.com/security/notices/USN-4684-1","label":"ubuntu.com/security/notices/USN-4684-1","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://github.com/tianocore/edk2/releases","label":"github.com/tianocore/edk2/releases","hostname":"github.com","tags":["WEB"]}],"lineage":{"upstream":["CVE-2018-12179","CVE-2018-12182","CVE-2018-12183","CVE-2019-0160","CVE-2019-0161","CVE-2019-14553","CVE-2019-14558","CVE-2019-14559","CVE-2019-14562","CVE-2019-14563","CVE-2019-14575","CVE-2019-14584","CVE-2019-14586","CVE-2019-14587"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2021-01-17T16:07:01.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:42:41.889Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T07:36:34.173Z","stale":false,"partial":false}}
