CVE-2026-18103: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in Red Hat Red Hat Enterprise Linux 6CVE-2026-18103 0 A buffer overflow vulnerability exists in the dhcp-server component of Red Hat Enterprise Linux 6. An attacker with network access to the OMAPI port (7911), if not secured with TSIG key authentication, can send a specially crafted lease creation request containing an overly long InfiniBand MAC address. This triggers a buffer overflow in the print_hw_addr() function, causing the dhcpd service to crash and preventing it from restarting without manual intervention, resulting in a persistent denial of service.
