iOS 18.6 and macOS Sequoia 15.6 fix a security bug exploited in Google Chrome

According to a report by Bleeping Computers, Apple has released security updates to address a high-severity vulnerability that has been exploited in zero-day attacks targeting Google Chrome users. This is being tracked as CVE-2025-6558; the security bug is due to the incorrect validation of untrusted input in the ANGLE (Almost Native Graphics Layer Engine) open-source graphics abstraction layer.

The flaw could allow remote attackers to execute arbitrary code using HTML pages created for that purpose, escaping Chrome's sandboxing. Google also addressed the issue in its latest security update for Chrome on desktop and mobile. Although initially in Safari, Apple said that the issue could cause unexpected crashes. However, later it was found out that Apple’s native browser wasn’t prone to these attacks.
