CVE 설명
In the Linux kernel, the following vulnerability has been resolved:
vduse: return compat ioctl results directly
The compat handler handles VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO, but
then calls the native handler. Their different command sizes make native
dispatch return -ENOIOCTLCMD.
For GET_FD, this overwrites receive_fd()'s return value after the
descriptor is installed, leaking one fd per call. Return handled compat
results directly and use native dispatch only for other commands.
