In the Linux kernel, the following vulnerability has been resolved:

vhost/vsock: Use kvmalloc/kvfree for larger packets.

When copying a large file over sftp over vsock, data size is usually 32kB, and kmalloc seems to fail to try to allocate 32 32kB regions.

Work around by doing kvmalloc instead.
