Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the net_dhcpv4_msg_type_name function. An attacker can cause a crash or potentially disclose adjacent memory contents by sending a crafted DHCP reply with an out-of-range message type value. This is only exploitable if the DHCPv4 log module is built at DEBUG level (CONFIG_NET_DHCPV4_LOG_LEVEL_DBG), which is not the default configuration.
