In the Linux kernel, the following vulnerability has been resolved:
ublk: check import_ubuf() return value
import_ubuf() can fail if the address range (provided by the userspace
ublk server) is outside the allowed user address space. Return that 0
bytes were copied if import_ubuf() fails rather than passing an
uninitialized struct iov_iter to ublk_copy_user_pages().
