  "description": "In the Linux kernel, the following vulnerability has been resolved:  vduse: fix memory corruption in vduse_dev_ioctl()  The \u0022config.offset\u0022 comes from the user.  There needs to a check to prevent it being out of bounds.  The \u0022config.offset\u0022 and \u0022dev-\u003Econfig_size\u0022 variables are both type u32.  So if the offset if out of bounds then the \u0022dev-\u003Econfig_size - config.offset\u0022 subtraction results in a very high u32 value.  The out of bounds offset can result in memory corruption.",
