CVE-2026-26011 is a critical heap out-of-bounds write vulnerability affecting Nav2 AMCL in ROS 2 Navigation Framework versions 1.3.11 and earlier. An unauthenticated attacker on the same ROS 2 DDS domain can trigger this by sending a specially crafted message to the /initialpose topic, leading to memory corruption. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low complexity, and potential for complete compromise (Confidentiality, Integrity, Availability). While the primary impact is a reliable denial of service, the memory corruption could allow for further exploitation. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
