Out-of-bounds write in the command interface of NVIDIA ConnectX SmartNICs and BlueField DPUs allows a local user holding virtual function (VF) access - typically a tenant inside a guest VM - to corrupt device memory via crafted input and potentially achieve arbitrary code execution on the network device itself. Because the CVSS scope is Changed (S:C), a successful exploit crosses the VF isolation boundary and threatens the host and other tenants, making this a serious multi-tenant/cloud isolation-breakout risk. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
