CVE-2024-36913

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails

In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.

VMBus code could free decrypted pages if set_memory_encrypted()/decrypted()
fails. Leak the pages if this happens.

The Linux kernel CVE team has assigned CVE-2024-36913 to this issue.
