Chrome’s Zero-Day Party: Google Patches Fifth Exploit of 2025!
Chrome zero-days are Google’s version of gremlins—just when you think you’ve fixed one, another pops up! In 2025, CVE-2025-6554 marks the fifth actively exploited Chrome zero-day patched by Google. It’s a type confusion issue in the V8 engine, proving once again that even browsers can have identity crises.

Hot Take:
Google Chrome has been so busy with zero-day vulnerabilities this year, it should probably invest in a good pair of running shoes. With CVE-2025-6554 marking the fifth time Chrome’s had to patch things up in 2025, it seems like the browser’s new favorite hobby is playing dodgeball with cyber threats. Maybe next year it can try something less stressful, like knitting!
