Cumulus Linux Lts
Monthly
Buffer overflow in the LLDP daemon of NVIDIA Cumulus Linux enables an unauthenticated attacker with Layer 2 network adjacency to achieve code execution by sending specially crafted LLDP frames. Both the GA track (all versions through 5.16) and LTS track (through 5.11.5 and 5.9.5 respectively) are confirmed affected. No active exploitation or public proof-of-concept code has been identified at time of analysis, though CISA SSVC rates the technical impact as total given that a successful exploit yields full switch compromise.
