What is CVE-2026-32706?

Prior to version 1.17.0-rc2, the PX4 autopilot's crsf_rc parser was vulnerable to a memory corruption issue. By accepting an oversized variable-length known packet and copying it into a fixed 64-byte global buffer without bounds checking, the vulnerability allowed an adjacent/raw-serial attacker to cause memory corruption, potentially leading to a system crash. This issue is addressed in version 1.17.0-rc2, which mitigates the risks associated with this flaw.
