      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: free pending qentry in smc_llc_flow_stop() before memset\n\nsmc_llc_flow_stop() resets a flow struct with a blind memset:\n\n\tspin_lock_bh(&lgr->llc_flow_lock);\n\tmemset(flow, 0, sizeof(*flow));\n\tflow->type = SMC_LLC_FLOW_NONE;\n\tspin_unlock_bh(&lgr->llc_flow_lock);\n\nIf flow->qentry is non-NULL at this point the pointer is overwritten without the\nallocation being freed, leaking one kmalloc object.\n\nA late-arriving duplicate CONFIRM_LINK or ADD_LINK_CONT message can set\nflow->qentry after the legitimate message has been consumed by the waiter via\nsmc_llc_flow_qentry_clr() (which NULLs the pointer but leaves flow->type\nnon-zero) but before the flow completes and smc_llc_flow_stop() runs.  In that\nwindow the duplicate is stashed into flow->qentry, and then lost when\nsmc_llc_flow_stop() zeros the struct.\n\nCall smc_llc_flow_qentry_del() inside the lock before the memset.\nsmc_llc_flow_qentry_del() already checks flow->qentry before freeing, so the\nnormal case where no entry is pending is a no-op.",
