A check\nwas already there in ethnl_ops_begin, but not wide enough.\n\nNote that the same issue cannot be seen on the ioctl version\n(__dev_ethtool) because the device reference is retrieved from within\nthe rtnl lock section there. Once dismantle started, the net device is\nunlisted and no reference will be found.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nsch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()\n\nWhen enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the\nchild qdisc\u0027s peek() operation before incrementing sch-\u003eq.qlen and\nsch-\u003eqstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may\ntrigger an immediate dequeue and potential packet drop. In such cases,\nqdisc_tree_reduce_backlog() is called, but the HFSC qdisc\u0027s qlen and backlog\nhave not yet been updated, leading to inconsistent queue accounting. This\ncan leave an empty HFSC class in the active list, causing further\nconsequences like use-after-free.\n\nThis patch fixes the bug by moving the increment of sch-\u003eq.qlen and\nsch-\u003eqstats.backlog before the call to the child qdisc\u0027s peek() operation.\nThis ensures that queue length and backlog are always accurate when packet\ndrops or dequeues are triggered during the peek.",
