    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ncsi: fix skb leak in error paths\n\nEarly return paths in NCSI RX and AEN handlers fail to release\nthe received skb, resulting in a memory leak.\n\nSpecifically, ncsi_aen_handler() returns on invalid AEN packets\nwithout consuming the skb. Similarly, ncsi_rcv_rsp() exits early\nwhen failing to resolve the NCSI device, response handler, or\nrequest, leaving the skb unfreed.",
