That\nreleases the wait_for_completion(&hif_dev->fw_done) in a concurrent\nath9k_hif_usb_disconnect(), which then kfree()s hif_dev. The trailing\ndev_info() in the frame that re-armed the request can therefore read freed\nmemory (hif_dev->udev, the first field of struct hif_device_usb):\n\n  BUG: KASAN: slab-use-after-free in ath9k_hif_request_firmware\n  Read of size 8 ... by task kworker/...\n   ath9k_hif_request_firmware\n   ath9k_hif_usb_firmware_cb           drivers/net/wireless/ath/ath9k/hif_usb.c:1247\n   request_firmware_work_func\n  Allocated by ...:\n   ath9k_hif_usb_probe                 drivers/net/wireless/ath/ath9k/hif_usb.c\n  Freed by ...:\n   ath9k_hif_usb_disconnect -> kfree   drivers/net/wireless/ath/ath9k/hif_usb.c\n\nThe fw_done barrier only makes disconnect wait for the firmware chain to\n*terminate*; it does not protect the outer ath9k_hif_request_firmware()\nframe that re-armed the request and keeps touching hif_dev afterwards.\n\nDrop the post-request dev_info(): it is the only use of hif_dev after the\nasync request is armed, and it is purely informational (the dev_err() on the\nfailure path runs only when request_firmware_nowait() did not arm a callback,\nso hif_dev is still alive there).\n\nThis was first reported by syzbot as a single, non-reproduced crash that was\nlater auto-obsoleted, and was independently rediscovered by the reFuzz fuzzer,\nwhich produced a C reproducer (USB-gadget connect/disconnect of an ath9k_htc\ndevice whose firmware download fails). The vulnerable code is unchanged and\nstill present in v7.1-rc6, where the slab-use-after-free reproduces under KASAN\nonce the (sub-microsecond) race window is widened.",
