Once again, this is another example of how poor these TLDR bots are. I asked a popular LLM (which people here love to hate) to summarize the article, and not only did I get an actual TLDR (< 150 words), it also included the most important piece of information:

GPUs from major suppliers including Apple, Intel, AMD, Qualcomm, Arm, and Nvidia are vulnerable to an attack allowing malicious websites to read sensitive visual data from other websites. The exploit, named GPU.zip, violates the "same origin policy", a fundamental internet security boundary. The vulnerability starts when a malicious site places a link in an iframe, an HTML element. While normally this policy prevents content interaction between sites, the data compression used by GPUs for performance optimization creates a side channel that can be exploited. To succeed, the attack requires loading a malicious page in Chrome or Edge; Firefox and Safari's operational differences protect them. Furthermore, the targeted page in the iframe should allow cross-origin embedding. Although many sites block this embedding using X-Frame-Options or Content-Security-Policy headers, some, like Wikipedia, don't. The current risk posed by GPU.zip is considered low, but the discovery emphasizes potential hardware-based side channels in security.
