  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm: Do not allow userspace to trigger kernel warnings in drm_gem_change_handle_ioctl()  Since GEM bo handles are u32 in the uapi and the internal implementation uses idr_alloc() which uses int ranges, passing a new handle larger than INT_MAX trivially triggers a kernel warning:  idr_alloc(): ... \tif (WARN_ON_ONCE(start \u003C 0)) \t\treturn -EINVAL; ...  Fix it by rejecting new handles above INT_MAX and at the same time make the end limit calculation more obvious by moving into int domain.",
