From b6f147a2d90765e68effe04c42f79875b33cd2af Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Wed, 27 Jun 2018 11:49:28 +0800 Subject: [PATCH] esp6: fix memleak on error path in esp6_input [ Upstream commit 7284fdf39a912322ce97de2d30def3c6068a418c ] This ought to be an omission in e6194923237 ("esp: Fix memleaks on error paths."). The memleak on error path in esp6_input is similar to esp_input of esp4. Fixes: e6194923237 ("esp: Fix memleaks on error paths.") Fixes: 3f29770723f ("ipsec: check return value of skb_to_sgvec always") Signed-off-by: Zhen Lei Signed-off-by: Steffen Klassert Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- net/ipv6/esp6.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/net/ipv6/esp6.c b/net/ipv6/esp6.c index 89910e2c10f4..f112fef79216 100644 --- a/net/ipv6/esp6.c +++ b/net/ipv6/esp6.c @@ -651,8 +651,10 @@ skip_cow: sg_init_table(sg, nfrags); ret = skb_to_sgvec(skb, sg, 0, skb->len); - if (unlikely(ret < 0)) + if (unlikely(ret < 0)) { + kfree(tmp); goto out; + } skb->ip_summed = CHECKSUM_NONE; -- 2.20.1
