+Subject: crypto: bcm - Verify GCM/CCM key length in setkey
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+From: Herbert Xu <herbert@gondor.apana.org.au>
+
+commit 10a2f0b311094ffd45463a529a410a51ca025f27 upstream.
+
+The setkey function for GCM/CCM algorithms didn't verify the key
+length before copying the key and subtracting the salt length.
+
+This patch delays the copying of the key til after the verification
+has been done.  It also adds checks on the key length to ensure
+that it's at least as long as the salt.
+
+Fixes: 9d12ba86f818 ("crypto: brcm - Add Broadcom SPU driver")

+Subject: crypto: qat - check cipher length for aead AES-CBC-HMAC-SHA
+
+From: Dominik Przychodni <dominik.przychodni@intel.com>
+
+commit 45cb6653b0c355fc1445a8069ba78a4ce8720511 upstream.
+
+Return -EINVAL for authenc(hmac(sha1),cbc(aes)),
+authenc(hmac(sha256),cbc(aes)) and authenc(hmac(sha512),cbc(aes))
+if the cipher length is not multiple of the AES block.
+This is to prevent an undefined device behaviour.
+
+Fixes: d370cec32194 ("crypto: qat - Intel(R) QAT crypto interface")
