CVE-2026-1579

38
FAUCET Score

CVE-2026-1579 is a critical vulnerability (CVSS 9.8) affecting the MAVLink communication protocol, particularly in implementations like PX4 Autopilot, when MAVLink 2.0 message signing is not enabled. An unauthenticated attacker with network access to the MAVLink interface can send arbitrary commands, including SERIAL_CONTROL, to gain interactive shell access. This low-complexity attack allows for a complete compromise of confidentiality, integrity, and availability of the affected system. While there is no evidence of active exploitation or public exploit code available, the vulnerability has received some community discussion and media coverage. Organizations utilizing MAVLink should immediately enable MAVLink 2.0 message signing to mitigate this severe risk.
