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