CVE-2024-38927

Summary

CVE-2024-38927 is a newly discovered vulnerability affecting Open Robotics Robotic Operating System 2 (ROS2) and Nav2 humble versions. The issue involves a use-after-free vulnerability in the nav2_amcl process, which can be triggered remotely by changing the value of the dynamic-parameter `/amcl do_beamskip`. This means an attacker can send a request to manipulate this parameter, causing memory that has already been freed to be accessed again, potentially leading to unpredictable behavior, crashes, or even code execution. It is important for users of these affected versions to apply the necessary patches as soon as possible to mitigate this risk.
