The call stack includes:\n- `dwc3_ep0_reset_state()`\n- `dwc3_ep0_stall_and_restart()`\n- `dwc3_ep0_out_start()`\n- `dwc3_remove_requests()`\n- `dwc3_gadget_del_and_unmap_request()`\n\nPath 2:\nAlso initiated from `dwc3_gadget_reset_interrupt()`, but through\n`dwc3_stop_active_transfers()`. The call stack includes:\n- `dwc3_stop_active_transfers()`\n- `dwc3_remove_requests()`\n- `dwc3_gadget_del_and_unmap_request()`\n\nPath 3:\nOccurs independently during `adb root` execution, which triggers\nUSB function unbind and bind operations. The sequence includes:\n- `gserial_disconnect()`\n- `usb_ep_disable()`\n- `dwc3_gadget_ep_disable()`\n- `dwc3_remove_requests()` with `-ESHUTDOWN` status\n\nPath 3 operates asynchronously and lacks synchronization with Paths\n1 and 2. When Path 3 completes, it disables endpoints and frees 'out'\nrequests. If Paths 1 or 2 are still processing these requests,\naccessing freed memory leads to a crash due to use-after-free conditions.\n\nTo fix this added check for request completion and skip processing\nif already completed and added the request status for ep0 while queue."}],"metrics":{},"references":[{"url":"https://git.kernel.org/stable/c/467add9db13219101f14b6cc5477998b4aaa5fe2","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/47de14d741cc4057046c9e2f33df1f7828254e6c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/67192e8cb7f941b5bba91e4bb290683576ce1607","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/7cfb62888eba292fa35cd9ddbd28ce595f60e139","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/afc0e34f161ce61ad351303c46eb57bd44b8b090","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/e4037689a366743c4233966f0e74bc455820d316","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/fa5eaf701e576880070b60922200557ae4aa54e1","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
