"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvduse: return compat ioctl results directly\n\nThe compat handler handles VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO, but\nthen calls the native handler. Their different command sizes make native\ndispatch return -ENOIOCTLCMD.\n\nFor GET_FD, this overwrites receive_fd()'s return value after the\ndescriptor is installed, leaking one fd per call. Return handled compat\nresults directly and use native dispatch only for other commands."
