Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the missing throttle threshold safety check by requiring validation of physical throttle stick inputs during critical mode switches to prevent uncontrolled ascent.

SI-17 Fail-safe Procedures good match

prevent

Implements fail-safe procedures for unsafe conditions during ARMED state mode transitions, such as automatic disarm or throttle limits, to avert flyaway incidents.

SI-2 Flaw Remediation good match

preventrecover

Requires identification and correction of the specific logic flaw in mode switching via patching, eliminating the vulnerability in affected PX4 versions.

NVD Description

PX4 Autopilot versions 1.12.x through 1.15.x contain a logic flaw in the mode switching mechanism. When switching from Auto mode to Manual mode while the drone is in the "ARMED" state (after landing and before the automatic disarm triggered by…

the COM_DISARM_LAND parameter), the system lacks a throttle threshold safety check for the physical throttle stick. This flaw can directly cause the drone to lose control, experience rapid uncontrolled ascent (flyaway), and result in property damage

Deeper analysisAI

CVE-2026-26741, published on 2026-03-10, is a logic flaw classified under CWE-862 in the mode switching mechanism of PX4 Autopilot versions 1.12.x through 1.15.x. The vulnerability arises when switching from Auto mode to Manual mode while the drone is in the "ARMED" state—specifically after landing and before the automatic disarm triggered by the COM_DISARM_LAND parameter. During this transition, the system lacks a throttle threshold safety check for the physical throttle stick, which can directly cause the drone to lose control, undergo rapid uncontrolled ascent (flyaway), and result in property damage. The issue carries a CVSS v3.1 base score of 8.1 (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).

An adjacent attacker (AV:A) can exploit this vulnerability with low attack complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:N). By timing or inducing a mode switch from Auto to Manual during the narrow post-landing ARMED window, and ensuring the physical throttle stick exceeds safe thresholds, the attacker can trigger the flyaway condition. This results in high integrity (I:H) and availability (A:H) impacts, with no confidentiality consequences (C:N), potentially leading to physical drone loss or damage.
