Google on Tuesday rolled out patches for Chrome browser for desktops to contain an actively exploited high-severity zero-day flaw in the wild.
Tracked as CVE-2022-2856, the issue has been described as a case of insufficient validation of untrusted input in Intents. Security researchers Ashley Shen and Christian Resell of Google Threat Analysis Group have been credited with reporting the flaw on July 19, 2022.
As is typically the case, the tech giant has refrained from sharing additional specifics about the shortcoming until a majority of the users are updated. “Google is aware that an exploit for CVE-2022-2856 exists in the wild,” it acknowledged in a terse statement.
The latest update further addresses 10 other security flaws, most of which relate to use-after-free bugs in various components such as FedCM, SwiftShader, ANGLE, and Blink, among others. Also fixed is a heap buffer overflow vulnerability in Downloads.
The development marks the fifth zero-day vulnerability in Chrome that Google has resolved since the start of the year –

- CVE-2022-1096 – Type confusion in V8
