New GPU Side Channel Vulnerability Impacts GPUs from Intel, AMD, Apple & Nvidia. A side-channel attack can leak sensitive visual data from modern GPU cards. The attack is referred to as "GPU.zip" and was published by four American universities. The attack exploits vendor-specific compression used by Intel and AMD. Compression is a known source of side-channel data leakages. The attack can steal sensitive visual data pixel-by-pixel. The attack demonstration was conducted on the Wikipedia site. The research paper recommends further study for detailed information. Patch Manager Plus can help protect against vulnerabilities.
