CVE-2024-37863Public exploitNetwork attack vector

Service interruption via unchecked AMCL distance parameter

Published Dec 5, 2024 · Updated Dec 6, 2024

Heap-buffer overflow in Navigation2 Humble's nav2_amcl process allows remote attackers to crash it via a crafted YAML parameter file. The node accepts a NaN laser_likelihood_max_dist value without finite-value validation and passes it to CachedDistanceMap, which derives an impossibly large heap allocation. The crafted configuration must reach AMCL and a laser scan must initialize its likelihood-field model; the demonstrated consequence is process abort and service interruption.
