  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: nci: assert requested protocol is valid\n\nThe protocol is used in a bit mask to determine if the protocol is\nsupported. Assert the provided protocol is less than the maximum\ndefined so it doesn't potentially perform a shift-out-of-bounds and\nprovide a clearer error for undefined protocols vs unsupported ones.",
