CVE-2026-97983

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.
