      "title": "media: pwc: Return queued buffers on start_streaming() failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: pwc: 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\npwc's start_streaming() had two early returns that hit this trap:\n-ENODEV when the USB device was already disconnected, and -ERESTARTSYS\nwhen mutex_lock_interruptible() was interrupted by a signal.  Call the\nexisting pwc_cleanup_queued_bufs() helper with VB2_BUF_STATE_QUEUED\nbefore returning (matching the state already used by the\npwc_isoc_init() error path in the same function).\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\").",
