Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

11895 vulnerabilities reference this CWE, most recent first.

Title
PX4 Autopilot through 1.17.0 Use-After-Free in load_mon
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.

Title
PX4 Autopilot through 1.17.0 Use-After-Free via Temperature Calibration Task Startup
Summary
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.
