Subject: [PATCH] orinoco: possible null pointer dereference in orinoco_rx_monitor()
Date: Sat, 20 May 2006 15:27:23 -0400	[thread overview]
Message-ID: <446F6D9B.1070500@gmail.com> (raw)

If the skb allocation fails, the current error path calls
dev_kfree_skb_irq() with a NULL argument. Also, 'err' is not being used.

Coverity CID: 275.
