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...
