Subject: [PATCH v1 0/1] Nitro Enclaves kernel driver issue fix

An issue was found in the Nitro Enclaves kernel driver codebase [1] included in
the v5.10 upstream Linux kernel. The fix for it has been tested on the AWS side.
The issue does not break the isolation or security of what is running inside the
enclave. Nitro Enclaves already assumes that the instance running the Nitro
Enclaves kernel driver is untrusted.

We would like to thank Mathias Krause from Open Source Security, Inc. for
reporting and providing a fix for this issue directly to AWS.

The patch will be merged into the latest upstream Linux kernel release and into
the v5.10+ stable kernel releases.

Thanks,
Andra
