Title
mptcp: pm: only decrement add_addr_accepted for MPJ req
Summary
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: only decrement add_addr_accepted for MPJ req Adding the following warning ... WARN_ON_ONCE(msk->pm.add_addr_accepted == 0) ... before decrementing the add_addr_accepted counter helped to find a bug when running the "remove single subflow" subtest from the mptcp_join.sh selftest. Removing a 'subflow' endpoint will first trigger a RM_ADDR, then the subflow closure. Before this patch, and upon the reception of the RM_ADDR, the other peer will then try to decrement this add_addr_accepted. That's not correct because the attached subflows have not been created upon the reception of an ADD_ADDR. A way to solve that is to decrement the counter only if the attached subflow was an MP_JOIN to a remote id that was not 0, and initiated by the host receiving the RM_ADDR.

MPTCP servers (IPPROTO_MPTCP listeners on cloud/mobile/edge systems) accept these from arbitrary internet clients.\nAC:L - The attacker fully controls both the MP_JOIN that creates the non-ADD_ADDR subflow and the subsequent RM_ADDR that removes it, with the address ID chosen by the attacker; no race, memory layout, or victim-side timing is involved. Default settings (kernel path manager, subflows_max=2, accept_subflow=true) suffice, making the underflow deterministic and repeatable.\nPR:N - MPTCP has no authentication layer above TCP \u2014 a client connecting to an MPTCP-enabled service, or a malicious server a client connects to, can drive this without any credentials or local account. No capability, namespace, or netlink access is needed anywhere along the path.\nUI:N - Against an MPTCP-enabled listening service the attacker initiates the connection and sends the MP_JOIN and RM_ADDR options itself. No victim action is required beyond the service already running.\nS:U - The corrupted state (msk-\u003epm.add_addr_accepted and pm.accept_addr) and all consequences remain within the kernel networking stack of the affected host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an arithmetic underflow of an internal accounting counter; it yields no out-of-bounds read, no kernel pointer exposure, and no path for reading memory the attacker should not see. Subflows forced open by the bypass still require the connection keys for MP_JOIN, so no session data is disclosed to third parties.\nI:L - A remote unauthenticated peer corrupts kernel path-manager state (counter wraps 0 \u2192 255 and accept_addr is forced true), bypassing the administrator-configured net.mptcp add_addr_accepted limit \u2014 including its default value of 0 meaning \"accept none\". This modifies protected kernel state and alters the host\u0027s path-management behavior, but grants no arbitrary write or control-flow influence.\nA:H - The underflowed counter defeats the sole resource-protection control on accepted address announcements, letting a remote peer repeatedly cycle MP_JOIN/RM_ADDR to refill the ADD_ADDR budget and drive unbounded attacker-directed subflow and socket creation from the victim. Sustained across many parallel connections this is a plausible resource-exhaustion denial of service, and the higher rating is taken given the uncertainty in bounding it."

Before this patch, and upon the reception of the\nRM_ADDR, the other peer will then try to decrement this\nadd_addr_accepted. That\u0027s not correct because the attached subflows have\nnot been created upon the reception of an ADD_ADDR.\n\nA way to solve that is to decrement the counter only if the attached\nsubflow was an MP_JOIN to a remote id that was not 0, and initiated by\nthe host receiving the RM_ADDR."

MPTCP servers (IPPROTO_MPTCP listeners on cloud/mobile/edge systems) accept these from arbitrary internet clients.\nAC:L - The attacker fully controls both the MP_JOIN that creates the non-ADD_ADDR subflow and the subsequent RM_ADDR that removes it, with the address ID chosen by the attacker; no race, memory layout, or victim-side timing is involved. Default settings (kernel path manager, subflows_max=2, accept_subflow=true) suffice, making the underflow deterministic and repeatable.\nPR:N - MPTCP has no authentication layer above TCP \u2014 a client connecting to an MPTCP-enabled service, or a malicious server a client connects to, can drive this without any credentials or local account. No capability, namespace, or netlink access is needed anywhere along the path.\nUI:N - Against an MPTCP-enabled listening service the attacker initiates the connection and sends the MP_JOIN and RM_ADDR options itself. No victim action is required beyond the service already running.\nS:U - The corrupted state (msk-\u003epm.add_addr_accepted and pm.accept_addr) and all consequences remain within the kernel networking stack of the affected host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an arithmetic underflow of an internal accounting counter; it yields no out-of-bounds read, no kernel pointer exposure, and no path for reading memory the attacker should not see. Subflows forced open by the bypass still require the connection keys for MP_JOIN, so no session data is disclosed to third parties.\nI:L - A remote unauthenticated peer corrupts kernel path-manager state (counter wraps 0 \u2192 255 and accept_addr is forced true), bypassing the administrator-configured net.mptcp add_addr_accepted limit \u2014 including its default value of 0 meaning \"accept none\". This modifies protected kernel state and alters the host\u0027s path-management behavior, but grants no arbitrary write or control-flow influence.\nA:H - The underflowed counter defeats the sole resource-protection control on accepted address announcements, letting a remote peer repeatedly cycle MP_JOIN/RM_ADDR to refill the ADD_ADDR budget and drive unbounded attacker-directed subflow and socket creation from the victim. Sustained across many parallel connections this is a plausible resource-exhaustion denial of service, and the higher rating is taken given the uncertainty in bounding it."
