Drivers: hv: vmbus: Don't free ring buffers that couldn't be re-encrypted
In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Don't free ring buffers that couldn't be re-encrypted 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. The VMBus ring buffer code could free decrypted/shared pages if set_memory_decrypted() fails. Check the decrypted field in the struct vmbus_gpadl for the ring buffers to decide whether to free the memory.
