The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 9eb2533e-4434-11f1-bb07-bc241121aa0a advisory. The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing...

CVE-2026-7424

CVE-2026-7424 describes an integer underflow in the DHCPv6 sub-option parser of FreeRTOS-Plus-TCP. The issue affects FreeRTOS-Plus-TCP versions before V4.4.1 and before V4.2.6, and is triggered when DHCPv6 is enabled. An adjacent network actor can exploit the underflow by sending a crafted DHCPv6...

ovn: OVN: Information disclosure via crafted DHCPv6 packets

A flaw was found in OVN Open Virtual Network. A remote attacker, by sending crafted DHCPv6 Dynamic Host Configuration Protocol for IPv6 SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the...
