CVE-2026-84698 1 Px4 1 Autopilot 2026-09-02 6.5 Medium
PX4 Autopilot contains a heap buffer overflow vulnerability in the sd_bench command that writes a four-byte block number into a user-supplied sized allocation. Attackers can invoke sd_bench with a block size below four bytes to overflow the heap buffer and potentially execute code or crash the system.
CVE-2026-1579 1 Px4 2 Autopilot, Px4-autopilot 2026-04-08 9.8 Critical
The MAVLink communication protocol does not require cryptographic authentication by default. When MAVLink 2.0 message signing is not enabled, any message -- including SERIAL_CONTROL, which provides interactive shell access -- can be sent by an unauthenticated party with access to the MAVLink interface. PX4 provides MAVLink 2.0 message signing as the cryptographic authentication mechanism for all MAVLink communication. When signing is enabled, unsigned messages are rejected at the protocol level.
