| CVE-2026-46433 | lldpd is an implementation of IEEE 802.1ab (LLDP). Prior to version 1.0.22, lldpd_decode() in src/daemon/lldpd.c strips 802.1Q VLAN tags from received Ethernet frames by calling memmove() to shift the frame payload 4 bytes left. The third argument (byte count) is s - 2 * ETHER_ADDR_LEN but should be s - 2 * ETHER_ADDR_LEN - 4, causing a 4-byte heap buffer over-read past the malloc(h_mtu) allocation when the received frame size equals the interface MTU. This issue has been patched in version 1.0. | [email protected] | 6.5 | 0.01% | 2026-06-09 | 2026-06-11 |
| CVE-2023-41910 | An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c. | [email protected] | 9.8 | 0.15% | 2023-09-05 | 2024-11-21 |
| CVE-2021-43612 | In lldpd before 1.0.13, when decoding SONMP packets in the sonmp_decode function, it's possible to trigger an out-of-bounds heap read via short SONMP packets. | [email protected] | 7.5 | 0.21% | 2023-04-15 | 2025-02-06 |
| CVE-2020-27827 | A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. | [email protected] | 7.5 | 0.50% | 2021-03-18 | 2025-12-03 |
| CVE-2015-8012 | lldpd before 0.8.0 allows remote attackers to cause a denial of service (assertion failure and daemon crash) via a malformed packet. | [email protected] | 7.5 | 0.73% | 2020-01-28 | 2024-11-21 |
| CVE-2015-8011 | Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. | [email protected] | 9.8 | 5.56% | 2020-01-28 | 2024-11-21 |
