  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: cortina: Count dropped frames as NAPI work\n\nThe RX loop only consumes budget when it successfully delivers a frame.\nError paths keep consuming descriptors without reducing the budget, so a\nstream of bad frames can process the entire receive ring in one poll.\n\nMove the budget accounting to a common end-of-frame path. This counts\neach completed frame as NAPI work whether it was delivered or dropped,\nmatching the behavior of the vendor driver.",
