From 471c3d7e4b83b98ec8c0d8e2d4b566c3b7f5e43c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix Heap-overflow in dawn ReflectEntryPointUsingTint

Note: The operators needed to be added so BindingSlot
can be used in std::set. The needed to be constexpr
so that the static_assert that converting a tint
nonSamplerBindingPoint turns into a dawn nonSamplerBindingPoint.
The clang-format off is needed because clang-format fails
on the code in BindingPoint.h

Original Bug Report

Heap-buffer-overflow/wild-read in dawn::native::`anonymous namespace'::ReflectEntryPointUsingTint

Tested on: Chromium: 141.0.7379.0 (Developer Build) (64-bit) OS: Windows 11 Version 24H2 (Build 26100.4946)

GPU-info: Integrated AMD Radeon Graphics of AMD Ryzen 5 5625U

To reproduce run attached .html with ‘–enable-experimental-web-platform-features’ flag.

chromium-141.0.7379.0-win64-asan\chrome.exe –enable-experimental-web-platform-features heap-buffer-overflow-dawnnativeReflectEntryPointUsingTint.html

Reproduces also on Ubuntu 22.04 with ‘–enable-unsafe-webgpu’, but doesn’t require ‘–enable-experimental-web-platform-features’.
