Subject: [PATCH net v1] net: ipv4: Use kfree_sensitive instead of kfree
Date: Mon, 17 Jul 2023 17:59:19 +0800 [thread overview]
Message-ID: <20230717095932.18677-1-machel@vivo.com> (raw)
key might contain private part of the key, so better use
kfree_sensitive to free it.
Fixes: 38320c70d282 ("[IPSEC]: Use crypto_aead and authenc in ESP")
Signed-off-by: Wang Ming <machel@vivo.com>
