{"schemaVersion":3,"id":"CVE-2025-14963","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability identified in the HX Agent driver file fekern.sys allowed a threat actor with local user access the ability to gain elevated system privileges. Utilization of a Bring Your Own Vulnerable Driver (BYOVD) was leveraged to gain access to the critical Windows process memory lsass.exe (Local Security Authority Subsystem Service). The fekern.sys is a driver file associated with the HX Agent (used in all existing HX Agent versions). The vulnerable driver installed in a product or a system running a fully functional HX Agent is, itself, not exploitable as the product’s tamper protection restricts the ability to communicate with the driver to only the Agent’s processes.","dates":{"published":"2026-02-24T17:11:06.812Z","modified":"2026-02-26T14:44:08.034Z","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":"4.0","versionLabel":"v4.0","source":"CVE.org","score":6.2,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":6.2,"severity":"medium","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"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}]},"epss":{"probability":0.00107,"percentile":0.01064,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0.006999999999999997,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.001},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00107,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00107,"percentile":0.01064}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.001,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00104,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00104,"pe
