CVE-2025-24934 (CNNVD-202510-2811)
中文标题:
FreeBSD 安全漏洞
英文标题:
SO_REUSEPORT_LB breaks connect(2) for UDP sockets
漏洞描述
中文描述:
FreeBSD是FreeBSD基金会的一套类Unix操作系统。 FreeBSD存在安全漏洞，该漏洞源于内核未检查连接状态即添加套接字至负载均衡组，且连接状态下仍匹配负载均衡组套接字，可能导致欺骗攻击。
英文描述:
Software which sets SO_REUSEPORT_LB on a socket and then connects it to a host will not directly observe any problems. However, due to its membership in a load-balancing group, that socket will receive packets originating from any host. This breaks the contract of the connect(2) and implied connect via sendto(2), and may leave the application vulnerable to spoofing attacks. The kernel failed to check the connection state of sockets when adding them to load-balancing groups. Furthermore, when looking up the destination socket for an incoming packet, the kernel will match a socket belonging to a load-balancing group even if it is connected, in violation of the contract that connected sockets are only supposed to receive packets originating from the connected host.
