CVE-2026-46433
A flaw was found in lldpd, an implementation of IEEE 802.1ab LLDP. A remote attacker on the adjacent network can send specially crafted Ethernet frames with 802.1Q VLAN Virtual Local Area Network tags. This can cause a 4-byte heap buffer over-read, leading to a denial of service DoS due to an...
CVE-2026-46433
lldpd is an implementation of IEEE 802.1ab LLDP. Prior to version 1.0.22, lldpddecode 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 ETHERADDRLEN but should be s - 2...
CVE-2026-46433
CVE-2026-46433 affects lldpd (LLDP implementation). Prior to version 1.0.22, lldpd_decode() incorrectly shifts frame payload when removing 802.1Q VLAN tags, using a length calculation that causes a 4-byte heap OOB read if the frame size equals the interface MTU. This vulnerability is fixed in ver...
