Thefallback is needed for listening and connecting sockets, but sockets remainin the bound table after connect(), so it can also return a non-listeningsocket.\nThe fallback does not validate the source address. In TCP_SYN_SENT, aRESPONSE from an unrelated source can transition the victim socket toTCP_ESTABLISHED while its stored remote address remains unchanged.Subsequent RW packets from that source are delivered through the samedestination-only fallback.\nThis was reproduced with capability-empty processes under different UIDs.The attacker discovered the target tuple through unprivileged AF_VSOCKsock_diag and caused the victim socket to read 16 attacker-chosen bytes;the intended peer-side socket read 0 of those 16 bytes.\nAdd vsock_check_source() to validate the transport, source port and sourceCID against the peer stored in a non-listening socket. The local transportis the CID exception because its packets are generated internally withVMADDR_CID_LOCAL as their source, including connections using CID aliases.\nUse the helper after lock_sock() in the virtio receive path.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99123https://git.kernel.org/stable/c/6cd829de69efd9ed3a53aa2421004a0396eb2bd7https://git.kernel.org/stable/c/e9bf92de436ba55f33eaa55d7008e68551123cfdhttps://git.kernel.org/stable/c/dee44f41f206becb41c492899c1996cfd7f82a1b#kernel
