Fixed a potential memory leak inside skb_ether_to_p80211() When the wep_encrypt() fails the code return 2 directly Which causes the p80211_wep->data dangling Add a kfree statement to reclaim that memory allocated Signed-off-by: Lynn Lei <lynnl.yet@gmail.com> --- drivers/staging/wlan-ng/p80211conv.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/staging/wlan-ng/p80211conv.c b/drivers/staging/wlan-ng/p80211conv.c index fc8ad33ade9f..c1b6d426bcad 100644 --- a/drivers/staging/wlan-ng/p80211conv.c +++ b/drivers/staging/wlan-ng/p80211conv.c @@ -213,6 +213,7 @@ int skb_ether_to_p80211(struct wlandevice *wlandev, u32 ethconv, netdev_warn(wlandev->netdev, "Host en-WEP failed, dropping frame (%d).\n", foo); + kfree(p80211_wep->data); return 2; } fc |= cpu_to_le16(WLAN_SET_FC_ISWEP(1)); -- 2.13.3
