Security News > 2022 > July > Google Patches Actively Exploited Chrome Bug

While people were celebrating the Fourth of July holiday in the United States, Google quietly rolled out a stable channel update for Chrome to patch an actively exploited zero-day vulnerability, the fourth such flaw the vendor has had to patch in its browser product so far this year.

Chrome 103 for Android and Version 103.0.5060.114 for Windows and Mac, outlined in separate blog posts published Monday, fix a heap buffer overflow flaw in WebRTC, the engine that gives the browser its real-time communications capability.

Google Chrome updates are pushed out without user intervention, so most users will be protected once patches are available.

In addition to fixing the zero-day buffer overflow flaw, the Chrome releases also patch a type confusion flaw in the V8 JavaScript engine tracked as CVE-2022-2295 and reported June 16 by researchers "Avaue" and "Buff3tts" at S.S.L., according to the post.

Another flaw patched in Monday's Chrome update is a use-after-free flaw in Chrome OS Shell reported by Khalil Zhani on May 19 and tracked as CVE-2022-2296, according to Google.

Prior to patching the Chrome V8 JavaScript engine flaws in March and April, Google in February already had patched a zero-day use-after-free flaw in Chrome's Animation component tracked as CVE-2022-0609 that was under active attack.
