Background + +SO_REUSEPORT_LB is a socket option, set by setsockopt(2), which allows multiple +TCP or UDP sockets to bind to the same socket address, creating a +load-balancing group. Incoming packets and connections are distributed evenly +among sockets in a group. This helps network services avoid scalability +bottlenecks caused by having a single TCP listening socket. In particular, it +is expected that sockets belonging to a load-balancing group will accept +packets from any source address. + +II. Problem Description + +Connected sockets are not intended to belong to load-balancing groups. +However, 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. + +Connected sockets are only supposed to receive packets originating from the +connected host. The above behavior violates this contract. + +III. Impact + +Software which sets SO_REUSEPORT_LB on a socket and then connects it to a host +will not 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. + +IV. Workaround + +No workaround is available. Software which does not use SO_REUSEPORT_LB is +not affected. + +V. Solution + +Upgrade your vulnerable system to a supported FreeBSD stable or +release / security branch (releng) dated after the correction date. + +Perform one of the following: + +1) To update your vulnerable system via a binary patch: + +Systems running a RELEASE version of FreeBSD on the amd64 or arm64 platforms, +or the i386 platform on FreeBSD 13, can be updated via the freebsd-update(8) +utility: + +# freebsd-update fetch +# freebsd-update install +# shutdown -r +10min "Rebooting for a security update" + +2) To update your vulnerable system via a source code patch: + +The following patches have been verified to apply to the applicable +FreeBSD release branches. + +a) Download the relevant patch from the location below, and verify the +detached PGP signature using your PGP utility. + +[FreeBSD 15.x] +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-15.patch +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-15.patch.asc +# gpg --verify netinet-15.patch.asc + +[FreeBSD 14.x] +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-14.patch +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-14.patch.asc +# gpg --verify netinet-14.patch.asc + +[FreeBSD 13.x] +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-13.patch +# fetch https://security.FreeBSD.org/patches/SA-25:09/netinet-13.patch.asc +# gpg --verify netinet-13.patch.asc + +b) Apply the patch.
