      "title": "media: msi2500: Return queued buffers on start_streaming() failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: msi2500: Return queued buffers on start_streaming() failure\n\nThe vb2 framework hands buffers to the driver via buf_queue() before\ncalling start_streaming().  If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nmsi2500_start_streaming() had five error paths that all hit this trap\nand were further tangled by ret-overwriting between calls:\n\n  - -ENODEV when the USB device was already disconnected\n  - -ERESTARTSYS when mutex_lock_interruptible() was interrupted\n  - msi2500_set_usb_adc() failure: ret was silently overwritten by\n    the next call (msi2500_isoc_init), so the error was lost entirely\n  - msi2500_isoc_init() failure: cleanup_queued_bufs was called, but\n    the function then fell through to msi2500_ctrl_msg() and again\n    masked the original error by overwriting ret\n  - msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,\n    leaving isoc URBs submitted with no way for the driver to consume\n    them\n\nConsolidate the error paths into a small goto chain.  Every failure\nnow stops the function, drains the queued-buffer list, and returns\nthe real error code.  The ctrl_msg failure path also rolls back the\npreceding msi2500_isoc_init() via msi2500_isoc_cleanup() before\nunlocking and draining.\n\nThe cleanup helper takes a vb2_buffer_state argument so that the\nstart_streaming error paths can pass VB2_BUF_STATE_QUEUED (as\nexpected by userspace on start_streaming failure) while stop_streaming\nkeeps its existing VB2_BUF_STATE_ERROR semantics.\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\").",
