Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: ncsi: fix skb leak in error paths<br />
<br />
Early return paths in NCSI RX and AEN handlers fail to release<br />
the received skb, resulting in a memory leak.<br />
<br />
Specifically, ncsi_aen_handler() returns on invalid AEN packets<br />
without consuming the skb. Similarly, ncsi_rcv_rsp() exits early<br />
when failing to resolve the NCSI device, response handler, or<br />
request, leaving the skb unfreed.
Impact
Base Score 3.x
