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(). (NVD)
