Description

In the Linux kernel, the following vulnerability has been resolved: mptcp: cope racing subflow creation in mptcp_rcv_space_adjust Additional active subflows - i.e. created by the in kernel path manager - are included into the subflow list before starting the 3whs. A racing recvmsg() spooling data received on an already established subflow would unconditionally call tcp_cleanup_rbuf() on all the current subflows, potentially hitting a divide by zero error on the newly created ones. Explicitly check that the subflow is in a suitable state before invoking tcp_cleanup_rbuf().

Affected configurations

• linux linux kernel (>= 5.10 < 6.1.119) • linux linux kernel (>= 6.2 < 6.6.63) • linux linux kernel (>= 6.7 < 6.11.10) • linux linux kernel 6.12
