  "details": "In the Linux kernel, the following vulnerability has been resolved:  rxrpc: Fix the ACK parser to extract the SACK table for parsing  Fix modification of the received skbuff in rxrpc_input_soft_acks() and a potential incorrect access of the buffer in a fragmented UDP packet (the packet would probably have to be deliberately pre-generated as fragmented) when AF_RXRPC tries to extract the contents of the SACK table by copying out the contents of the SACK table into a buffer before attempting to parse  AF_RXRPC assumes that it can just call skb_condense() and then validly access the SACK table from skb-\u003edata and that it will be a flat buffer - but skb_condense() can silently fail to do anything under some circumstances.  Note that whilst rxrpc_input_soft_acks() should be able to parse extended ACKs, the rest of AF_RXRPC doesn't currently support that.  Further, there's then no need to call skb_condense() in rxrpc_input_ack(), so don't.",
