Description

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix refcount leak in nvmet_sq_create() In nvmet_sq_create(), a reference on the ctrl is taken via kref_get_unless_zero() before calling nvmet_check_sqid(). If nvmet_check_sqid() fails, the function returns the error directly without releasing the reference, leading to a leak. Fix this by jumping to the "ctrl_put" label, which already performs the necessary nvmet_ctrl_put(ctrl). This ensures the reference is properly released on this error path.
