Details

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: fix potential memory corruption in nvmetcprecvpdu() nvmetcprecvpdu() doesn't check the validity of the header length. When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvmetcpverify_hdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest. Fix this by rejecting packets with an unexpected header length.
