{"id":"CVE-2026-26742","details":"PX4 Autopilot versions 1.12.x through 1.15.x contain a protection mechanism failure in the \"Re-arm Grace Period\" logic. The system incorrectly applies the in-air emergency re-arm logic to ground scenarios. If a pilot switches to Manual mode and re-arms within 5 seconds (default configuration) of an automatic landing, the system bypasses all pre-flight safety checks, including the throttle threshold check. This allows for an immediate high-thrust takeoff if the throttle stick is raised, leading to loss of control.","modified":"2026-03-14T15:06:03.052412Z","published":"2026-03-10T19:17:17.280Z","references":[{"type":"EVIDENCE","url":"https://github.com/npuwyw/PX4-Autopilot/blob/audit-v1.12.3-mode-transition-logic-flaw/PX4_Autopilot_Mode_Switching_Logic_Vulnerability.md"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/px4/px4-autopilot","events":[{"introduced":"9524e8ec032c9c4c9cd8b8860a1675ab998e9997"},{"fixed":"6ea3539157ca358c70a515878b77077af7d4611d"}],"database_specific":{"versions":[{"introduced":"1.12.0"},{"fixed":"1.16.0"}]}}],"versions":["v1.12.0","v1.12.0-rc1","v1.13.0-alpha1","v1.13.0-beta1","v1.14.0-beta1","v1.14.0-beta2","v1.15.0-alpha1","v1.15.0-beta1","v1.16.0-alpha1","v1.16.0-alpha2","v1.16.0-beta1","v1.16.0-rc1","v1.16.0-rc2","v1.16.0-rc3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-26742.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"}]}
