From fed07d3eb8a8d9fcc0e455175a89bc6445d6faed Mon Sep 17 00:00:00 2001 From: Wang Hai Date: Mon, 14 Oct 2024 22:59:01 +0800 Subject: [PATCH] net: bcmasp: fix potential memory leak in bcmasp_xmit() The bcmasp_xmit() returns NETDEV_TX_OK without freeing skb in case of mapping fails, add dev_kfree_skb() to fix it.
