{"schemaVersion":3,"id":"CVE-2021-44149","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An issue was discovered in Trusted Firmware OP-TEE Trusted OS through 3.15.0. The OPTEE-OS CSU driver for NXP i.MX6UL SoC devices lacks security access configuration for wakeup-related registers, resulting in TrustZone bypass because the NonSecure World can perform arbitrary memory read/write operations on Secure World memory. This involves a v cycle.","dates":{"published":"2021-12-07T20:59:43.000Z","modified":"2024-08-04T04:17:24.901Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.8,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.6,"severity":"medium","vector":"AV:L/AC:L/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0035,"percentile":0.27194,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.011000000000000029,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00339},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0035,"percentile":0.27194}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00339,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0035,"percentile":null},{"date":"2026-
