Pending analysis

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
virt: sev-guest: Explicitly leak pages in unknown state<br />
<br />
When set_memory_{encrypted,decrypted}() fail, the user cannot know at which<br />
point the function failed, meaning that the pages are left in an unknown state<br />
from the point of view of the caller.<br />
<br />
Since the pages may be left in an unencrypted state, they are not suitable for<br />
general use, and cannot be returned safely to the buddy allocator. Avoid the<br />
issue by never freeing the pages, and then do the proper accounting by calling<br />
snp_leak_pages().
