-Subject: [PATCH] nvme: fix out-of-bounds access to the CMB
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Because the CMB BAR has a min_access_size of 2, if you read the last
-byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
-error.  This is CVE-2018-16847.
-
-Another way to fix this might be to register the CMB as a RAM memory
-region, which would also be more efficient.  However, that might be a
-change for big-endian machines; I didn't think this through and I don't
-know how real hardware works.  Add a basic testcase for the CMB in case
-somebody does this change later on.
