Summary
CVE-2026-46433 affecting package lldpd for versions less than 1.0.22-1
Details

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 * ETHERADDRLEN - 4, causing a 4-byte heap buffer over-read past the malloc(hmtu) allocation when the received frame size equals the interface MTU. This issue has been patched in version 1.0.22.
