Summary

ublk: Validate SQE128 flag before accessing the cmd

Details

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

ublk: Validate SQE128 flag before accessing the cmd

ublkctrlcmddump() accesses (header *)sqe->cmd before IOURINGFSQE128 flag check. This could cause out of boundary memory access.

Move the SQE128 flag check earlier in ublkctrluring_cmd() to return -EINVAL immediately if the flag is not set.
