                "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: fix race between delayed_work() and ceph_monc_stop()\n\nThe way the delayed work is handled in ceph_monc_stop() is prone to\nraces with mon_fault() and possibly also finish_hunting().  Both of\nthese can requeue the delayed work which wouldn't be canceled by any of\nthe following code in case that happens after cancel_delayed_work_sync()\nruns -- __close_session() doesn't mess with the delayed work in order\nto avoid interfering with the hunting interval logic.  This part was\nmissed in commit b5d91704f53e (\"libceph: behave in mon_fault() if\ncur_mon < 0\") and use-after-free can still ensue on monc and objects\nthat hang off of it, with monc->auth and monc->monmap being\nparticularly susceptible to quickly being reused.\n\nTo fix this:\n\n- clear monc->cur_mon and monc->hunting as part of closing the session\n  in ceph_monc_stop()\n- bail from delayed_work() if monc->cur_mon is cleared, similar to how\n  it's done in mon_fault() and finish_hunting() (based on monc->hunting)\n- call cancel_delayed_work_sync() after the session is closed"
