  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nmptcp: pm: only decrement add_addr_accepted for MPJ req\nAdding the following warning ...\nWARN_ON_ONCE(msk->pm.add_addr_accepted == 0)\n... before decrementing the add_addr_accepted counter helped to find a\nbug when running the \"remove single subflow\" subtest from the\nmptcp_join.sh selftest.\nRemoving a 'subflow' endpoint will first trigger a RM_ADDR, then the\nsubflow closure. Before this patch, and upon the reception of the\nRM_ADDR, the other peer will then try to decrement this\nadd_addr_accepted. That's not correct because the attached subflows have\nnot been created upon the reception of an ADD_ADDR.\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." ],
