Description
In the Linux kernel, the following vulnerability has been resolved: ublk: Validate SQE128 flag before accessing the cmd ublk_ctrl_cmd_dump() accesses (header *)sqe->cmd before IO_URING_F_SQE128 flag check. This could cause out of boundary memory access. Move the SQE128 flag check earlier in ublk_ctrl_uring_cmd() to return -EINVAL immediately if the flag is not set.
