Cumulus Linux Ga
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.
Local privilege escalation in NVIDIA Cumulus Linux exposes network switch operating systems to full compromise by unprivileged local users. The flaw resides in the user management component, where improper privilege assignment (CWE-250) allows a low-privileged authenticated user to escalate to higher privilege levels - likely root - with low attack complexity and no user interaction required. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the CVSS 7.8 High score reflects the full triad impact once local access is obtained.
