CVE-2026-86713
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
PX4 Autopilot through 1.17.0 contains a use-after-free vulnerability in the load_mon module's stop path where exit_and_cleanup() deletes the LoadMon object and frees the performance counter before perf_end() attempts to access it. Attackers can trigger this vulnerability by issuing the load_mon stop command from any PXH or MAVLink shell, causing reads and writes through freed memory that corrupt heap objects and destabilize the flight stack.
Risk Assessment
The vulnerability may allow an attacker to execute arbitrary code or destabilize the autopilot system, which in the case of drones or aircraft could lead to catastrophic consequences, including loss of vehicle control.
Recommendation
Upgrade PX4 Autopilot to a version later than 1.17.0 that includes a fix for this vulnerability.
Other vulnerabilities in PX4 Autopilot
See all- CVE-2026-86714Medium
PX4 Autopilot through 1.17.0 contains a stack buffer over-read vulnerability in the netman system command that fails to validate interface name length. Attackers can supply interface names of 74 bytes or more via the -i option to read beyond buffer boundaries, leaking stack memory to console output or writing it into persistent network configuration files.
- CVE-2026-86097Medium
PX4 Autopilot through 1.17.0 contains a null pointer dereference vulnerability in param_set_default_file() and param_set_backup_file() functions that allows attackers to crash the autopilot process. Attackers can invoke 'param select' or 'param select-backup' commands with no path argument from any PX4 shell to trigger the crash.
- CVE-2026-86096Medium
PX4 Autopilot through 1.17.0 contains a use-after-free vulnerability in TemperatureCalibration::start() due to a race condition between task spawning and object deletion. Attackers can trigger the calibration process via shell commands to write to freed heap memory, corrupting unrelated objects or allocator metadata and destabilizing heap operations.
- CVE-2026-84698Medium
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.
