As ZDNet reports, Chrome 88 fixes a zero-day vulnerability known as CVE-2021-21148. It was reported by security researcher Mattias Buelens on Jan. 24, but Google discovered it was being exploited by hackers before the vulnerability could be patched out of the browser. The exploit allowed Chrome users to be targeted by malicious code thanks to a memory corruption problem in Google's V8 JavaScript engine, which forms part of the Chrome browser. Although Google hasn't confirmed it, the exploit is thought to be what allowed security researchers to be targeted by North Korean hackers on social media last month.
