Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
net: ncsi: fix skb leak in error paths
Early return paths in NCSI RX and AEN handlers fail to release the received skb, resulting in a memory leak.
Specifically, ncsi_aen_handler() returns on invalid AEN packets without consuming the skb. Similarly, ncsi_rcv_rsp() exits early when failing to resolve the NCSI device, response handler, or request, leaving the skb unfreed.
