CVE-2026-24184: CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in NVIDIA Cumulus Linux GA
NVIDIA Cumulus Linux contains a vulnerability in the Link Layer Discovery Protocol (LLDP) daemon component, where an unauthenticated attacker on an adjacent network could cause buffer overflow by sending crafted LLDP frames. A successful exploit of this vulnerability might lead to code execution.
AI Analysis
Technical Summary
CVE-2026-24184 is a classic buffer overflow vulnerability (CWE-120) in the LLDP daemon component of NVIDIA Cumulus Linux GA. This flaw allows an unauthenticated attacker with adjacent network access to send crafted LLDP frames that overflow a buffer, which may result in arbitrary code execution. The vulnerability has a CVSS 3.1 base score of 7.5, reflecting high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation could lead to remote code execution by an unauthenticated attacker on an adjacent network, impacting confidentiality, integrity, and availability of the affected system. This could allow the attacker to execute arbitrary code with the privileges of the LLDP daemon.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the adjacent network where possible to limit exposure to crafted LLDP frames.
