  "summary": "dpaa2-eth: put MAC endpoint device on disconnect",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-eth: put MAC endpoint device on disconnect\n\nfsl_mc_get_endpoint() returns the MAC endpoint device with a reference\ntaken through device_find_child(). The Ethernet connect path stores that\ndevice in mac->mc_dev and keeps it for the lifetime of the connected MAC\nobject.\n\nHowever, the disconnect path only disconnects and closes the MAC before\nfreeing the dpaa2_mac object. It does not drop the endpoint device\nreference stored in mac->mc_dev, so every successful connect leaks that\ndevice reference when the MAC is later disconnected.\n\nDrop the endpoint device reference after closing the MAC and before\nfreeing the dpaa2_mac object.",
