      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work\n\nWhen the sqpoll is exiting and cancels pending work items, it may need\nto run task_work. If this happens from within io_uring_cancel_generic(),\nthen it may be under waiting for the io_uring_task waitqueue. This\nresults in the below splat from the scheduler, as the ring mutex may be\nattempted grabbed while in a TASK_INTERRUPTIBLE state.\n\nEnsure that the task state is set appropriately for that, just like what\nis done for the other cases in io_run_task_work().\n\ndo not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000029387fd2>] prepare_to_wait+0x88/0x2fc\nWARNING: CPU: 6 PID: 59939 at kernel/sched/core.c:8561 __might_sleep+0xf4/0x140\nModules linked in:\nCPU: 6 UID: 0 PID: 59939 Comm: iou-sqp-59938 Not tainted 6.12.0-rc3-00113-g8d020023b155 #7456\nHardware name: linux,dummy-virt (DT)\npstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\npc : __might_sleep+0xf4/0x140\nlr : __might_sleep+0xf4/0x140\nsp : ffff80008c5e7830\nx29: ffff80008c5e7830 x28: ffff0000d93088c0 x27: ffff60001c2d7230\nx26: dfff800000000000 x25: ffff0000e16b9180 x24: ffff80008c5e7a50\nx23: 1ffff000118bcf4a x22: ffff0000e16b9180 x21: ffff0000e16b9180\nx20: 000000000000011b x19: ffff80008310fac0 x18: 1ffff000118bcd90\nx17: 30303c5b20746120 x16: 74657320313d6574 x15: 0720072007200720\nx14: 0720072007200720 x13: 0720072007200720 x12: ffff600036c64f0b\nx11: 1fffe00036c64f0a x10: ffff600036c64f0a x9 : dfff800000000000\nx8 : 00009fffc939b0f6 x7 : ffff0001b6327853 x6 : 0000000000000001\nx5 : ffff0001b6327850 x4 : ffff600036c64f0b x3 : ffff8000803c35bc\nx2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff0000e16b9180\nCall trace:\n __might_sleep+0xf4/0x140\n mutex_lock+0x84/0x124\n io_handle_tw_list+0xf4/0x260\n tctx_task_work_run+0x94/0x340\n io_run_task_work+0x1ec/0x3c0\n io_uring_cancel_generic+0x364/0x524\n io_sq_thread+0x820/0x124c\n ret_from_fork+0x10/0x20",
