A Chrome 104 update announced by Google on Tuesday patches 11 vulnerabilities, including a zero-day that has been exploited in attacks.
The company described the exploited flaw as a high-severity issue related to insufficient validation of untrusted input in the Intents component. The security hole is tracked as CVE-2022-2856.
Google has not shared any information about the attacks, but noted that researchers of the company’s Threat Analysis Group reported the vulnerability on July 19.
This is the fifth Chrome zero-day patched by the internet giant in 2022. Exploitation of the fourth zero-day, which came to light in early July, has been linked to Israeli spyware company Candiru and used in targeted attacks aimed at entities in the Middle East.
In March, Google admitted that there has been a surge in Chrome zero-day exploitation. The company believes several factors have contributed to this trend, including the fact that attackers often have to combine multiple flaws for a single exploit.
The latest Chrome update also patches a critical use-after-free bug discovered by a Google Project Zero researcher, and five other high-severity issues identified by Google’s own employees or by external researchers. These external researchers each earned $5,000 or $7,000 for their findings.
Chrome 104.0.5112.101 also resolves three medium-severity issues, including two that earned researchers $3,000 and $2,000.
