{"schemaVersion":3,"id":"CVE-2019-17061","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Bluetooth Low Energy (BLE) stack implementation on Cypress PSoC 4 through 3.62 devices does not properly restrict the BLE Link Layer header and executes certain memory contents upon receiving a packet with a Link Layer ID (LLID) equal to zero. This allows attackers within radio range to cause deadlocks, cause anomalous behavior in the BLE state machine, or trigger a buffer overflow via a crafted BLE Link Layer frame.","dates":{"published":"2020-02-10T20:17:23.000Z","modified":"2024-08-05T01:33:16.274Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":6.1,"severity":"medium","vector":"AV:A/AC:L/Au:N/C:N/I:N/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00881,"percentile":0.58488,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00881},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00881,"percentile":0.58488}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00881,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00881,"percentile":nu
