But *before*\nkill_and_confirm of sq->ref (i.e. the admin connect managed to get an sq\nlive reference). In this case, sq->ctrl was allocated however after it was\ncaptured in a local variable in nvmet_sq_destroy.\nThis prevented the final reference drop on the ctrl.\n\nSolve this by re-capturing the sq->ctrl after all inflight request has\ncompleted, where for sure sq->ctrl reference is final, and move forward\nbased on that.\n\nThis issue was observed in an environment with many hosts connecting\nmultiple ctrls simoutanuosly, creating a delay in allocating a ctrl\nleading up to this race window."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected",
