Summary
In the Linux kernel, the following vulnerability has been resolved: ublk: don't allow user copy for unprivileged device UBLK_F_USER_COPY requires userspace to call write() on ublk char device for filling request buffer, and unprivileged device can't be trusted. So don't allow user copy for unprivileged device.
