  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  net: ethernet: cortina: Carry over frag counter...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: ethernet: cortina: Carry over frag counter  The gmac_rx() NAPI poll function assembles packets in an SKB from a ring buffer.  If the ring buffer gets completely emptied during a poll cycle, we exit gmac_rx(), but the packet is not yet completely assembled in the SKB, yet the fragment counter frag_nr is reset to zero on the next invocation.  Solve this by making the RX fragment counter a part of the port struct, and carry it over between invocations.  Reset the fragment counter only right after calling napi_gro_frags(), on error (after calling napi_free_frags()) or if stopping the port.  Reset it in some place where not strictly necessary just to emphasize what is going on.  This was found by Sashiko during normal patch review.",
