      "title": "rxrpc: Fix potential UAF after skb_unshare() failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix potential UAF after skb_unshare() failure\n\nIf skb_unshare() fails to unshare a packet due to allocation failure in\nrxrpc_input_packet(), the skb pointer in the parent (rxrpc_io_thread())\nwill be NULL'd out.  This will likely cause the call to\ntrace_rxrpc_rx_done() to oops.\n\nFix this by moving the unsharing down to where rxrpc_input_call_event()\ncalls rxrpc_input_call_packet().  There are a number of places prior to\nthat where we ignore DATA packets for a variety of reasons (such as the\ncall already being complete) for which an unshare is then avoided.\n\nAnd with that, rxrpc_input_packet() doesn't need to take a pointer to the\npointer to the packet, so change that to just a pointer.",
