Detailsinfo

A vulnerability has been found in PX4 Autopilot up to 1.12.x/1.15.x and classified as problematic. This vulnerability affects an unknown function of the component Configuration Handler. The manipulation with an unknown input leads to a protection mechanism vulnerability. The CWE definition for the vulnerability is CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. The impact remains unknown. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-26742 since 02/16/2026. The exploitation appears to be difficult.
