CVE-2026-46433 lldpd: Heap OOB Read in VLAN Decapsulation memmove

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...
