Google has released a security update for Chrome to address multiple vulnerabilities, including a high-severity sandbox escape flaw (CVE-2025-6558) that is actively being exploited. Users are urged to update to version 138.0.7204.157/.158 to mitigate risks, as the vulnerability allows attackers to execute arbitrary code through specially crafted HTML. This marks the fifth actively exploited flaw fixed in Chrome this year, following several others related to the V8 engine and browser security.
