In 2025, Google Chrome faced serious Chrome issues and cybersecurity vulnerabilities Seven key vulnerabilities endanger millions of users, risking data theft, ransomware, and system hijacking. These flaws preyed on weaknesses in Chrome’s design, especially its V8 JavaScript engine. This situation shows how advanced cyberattacks have become.
The Chrome issues found in 2025 highlighted systemic risks in the browser’s design. They also showed the increasing boldness of threat actors. Below, we look at the technical and operational factors that made these threats worse. Malicious Chrome extensions also preyed on security gaps. Attackers used hacked add-ons to inject harmful scripts. They stole credentials and changed how browsers worked.
The seven vulnerabilities in the 2025 CVE system included zero-day exploits. These Chrome issues evolved from outdated bugs, repurposed by modern threat actors.
Attackers exploited these weaknesses to bypass Chrome’s sandboxing. They compromised user data and hijacked enterprise networks. The severity scores (CVSS) ranged from 7.8 to 9.8, showing their potential for disruption.
Chrome’s V8 JavaScript engine processes code with remarkable speed. In 2025, it became a target for attackers. JIT compilation and memory optimization are efficient. But they can also lead to risks, such as heap overflows and type mismatches.
For instance, CVE-2025-1920 preyed on V8’s performance tuning. Small coding mistakes let attackers change data types and run arbitrary code. Even with Google’s “memory-safe” efforts, the engine’s complexity made it hard to close all attack paths. This brings up a key point: we need to balance speed and security.
The 2025 vulnerabilities came from different sources and had various impacts. They all shared one key aspect: they exploited memory-related weaknesses. The following section breaks down seven critical Chrome issues that posed significant risks in 2025.
1. CVE-2025-0611 – Object Corruption and Heap Corruption This vulnerability is one of the many Chrome issues tied to how the browser manages JavaScript objects in its memory heap. Attackers crafted scripts that forced the browser to dereference invalid pointers. This action corrupted nearby memory areas. When exploited, heap corruption allows attackers to overwrite important data structures. These structures include function pointers, which let them alter the execution flow.
A phishing campaign exploited this flaw. It installed keyloggers on devices that visited the affected news sites. Google addressed the problem by enhancing object lifecycle management.
2. CVE-2025-0612 – Out-of-Bounds Memory Corruption Chrome issues with bounds checking allowed attackers to write data outside the allowed memory buffers. These flaws allowed attackers to write data outside the allowed memory buffers. Hackers exploited JavaScript’s loose typing. They injected large arrays into functions like `Array.prototype.sort()`. This caused buffer overflows. As a result, the renderer process became unstable, leading to crashes or silent data leaks.
Cybersecurity firm Kaspersky connected this exploit to a credential-harvesting operation targeting SaaS platforms. The fix addressed these Chrome issues by applying stricter bounds validation and isolating heap compartments for high-risk functions.
3. CVE-2025-1920 – Type Confusion Vulnerability in V8 Type confusion occurred when V8 misidentified an object’s data type during JIT compiling. Attackers tricked the compiler by making objects appear as harmless integers. Later, they reinterpreted these as executable pointers. This bypassed Chrome’s Control Flow Integrity (CFI) protections. It sometimes let attackers gain kernel-level access.
The ransomware group DarkHydrus exploited this flaw to encrypt government databases in Europe. Google responded by improving type-checking logic and adding runtime assertions.
4. CVE-2025-2135 – Additional Type Confusion Issues This flaw is part of a broader set of Chrome issues and relates to CVE-2025-1920. It affected V8’s handling of “hidden classes,” which optimize property access. Attackers tampered with class transitions, leading to mismatched object layouts. This allowed them to overwrite virtual method tables (vTables). They used this method to deploy fileless malware.
Enterprises that use Chrome for cloud infrastructure face higher risks due to these persistent Chrome issues. Attackers target authenticated sessions to navigate across networks.
5. CVE-2025-2136 – Use-After-Free flaw in Chrome Inspector Chrome’s built-in developer tools became an unexpected target. The Inspector component failed to release memory after debugging sessions. This created dangling pointers. Attackers lured developers to malicious sites and triggered these pointers. They ran code in the privileged Inspector process. This access let them steal sensitive debugging data, such as authentication tokens. A financial institution in Asia reported losses of $2 million. Attackers exploited this flaw to manipulate transaction APIs.
6. CVE-2025-2137 – Out-of-Bounds Read in V8 This vulnerability allowed attackers to read uninitialized memory from V8’s heap. They designed special TypedArrays to retrieve leftover data. This includes things like session cookies and encryption keys. One exploit campaign siphoned AWS credentials from DevOps tools, leading to cryptojacking incidents. Google mitigated this by initializing memory regions before use and segmenting sensitive data.
7. CVE-2025-24201 – Remote Code Execution Exploited in the Wild This year’s most dangerous flaw is an RCE exploit spread through malvertising networks. It merges a V8-type confusion bug with a sandbox escape to run shellcode on target devices. The Conti ransomware group used it in their attacks. This caused major outages in healthcare systems. Google released an emergency update within 72 hours. However, organizations with slow patch cycles faced long breaches.
Mitigation Strategies and Cybersecurity Best Practices To address Chrome issues and 2025 vulnerabilities, we need technical fixes and user education. Here are the steps to reduce similar risks in the future.
Security Patch Management and Browser Updates Automate updates to close security gaps on time. Use tools like Chrome Enterprise Recommended policies for scheduled updates and testing. Subscribe to CVE alerts and join Google’s Advanced Protection Program (APP).
Implementing Cybersecurity Best Practices Adopting zero-trust principles is very important, beyond using patches. This means setting up Chrome with strict site isolation. Also, disable unnecessary APIs like WebUSB. Use reputable extensions to block harmful scripts.
