Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
In CoCo VMs, it is possible for the untrusted host to cause
set memory encrypted() or set memory decrypted() to fail, resulting in shared memory. Callers need to handle these errors to avoid returning decrypted memory to the page allocator, which could lead to functional or security issues. A field has been added to struct vmbus gpadl to track the decryption status of buffers, allowing callers to determine whether to free or leak pages.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
