      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: cortina: Carry over frag counter\n\nThe gmac_rx() NAPI poll function assembles packets in an\nSKB from a ring buffer.\n\nIf the ring buffer gets completely emptied during a poll cycle,\nwe exit gmac_rx(), but the packet is not yet completely\nassembled in the SKB, yet the fragment counter frag_nr is\nreset to zero on the next invocation.\n\nSolve this by making the RX fragment counter a part of the\nport struct, and carry it over between invocations.\n\nReset the fragment counter only right after calling\nnapi_gro_frags(), on error (after calling napi_free_frags())\nor if stopping the port.\n\nReset it in some place where not strictly necessary just to\nemphasize what is going on.\n\nThis was found by Sashiko during normal patch review.",
