| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmcb: fix error handling in mcb_alloc_bus()\n\nThere are two bugs:\n1) If ida_simple_get() fails then this code calls put_device(carrier)\n but we haven't yet called get_device(carrier) and probably that\n leads to a use after free.\n2) After device_initialize() then we need to use put_device() to\n release the bus. This will free the internal resources tied to the\n device and call mcb_free_bus() which will free the rest." |
