      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: vub300: fix use-after-free on disconnect\n\nThe vub300 driver maintains an explicit reference count for the\ncontroller and its driver data and the last reference can in theory be\ndropped after the driver has been unbound.\n\nThis specifically means that the controller allocation must not be\ndevice managed as that can lead to use-after-free.\n\nNote that the lifetime is currently also incorrectly tied the parent USB\ndevice rather than interface, which can lead to memory leaks if the\ndriver is unbound without its device being physically disconnected (e.g.\non probe deferral).\n\nFix both issues by reverting to non-managed allocation of the controller.",
