Google has released a crucial security update for its Chrome browser, addressing multiple high-severity vulnerabilities that could allow attackers to execute arbitrary code or bypass security measures. This update, part of the Stable Channel release (version 134.0.6998.88/.89 for Windows and Mac and 134.0.6998.88 for Linux), includes essential patches to protect users from emerging cyber threats.
If left unpatched, these vulnerabilities could be exploited through malicious websites, leading to system compromise. Therefore, it is critical for users and organizations to update Chrome immediately.
Key Security Vulnerabilities Fixed in the Latest Chrome Update
1. Type Confusion Vulnerabilities in V8 (CVE-2025-1920 & CVE-2025-2135)
Two of the most serious flaws patched in this update are type confusion vulnerabilities found in Chrome’s V8 JavaScript engine.
- CVE-2025-1920 – Reported by Excello s.r.o., this flaw could allow attackers to manipulate memory access, leading to arbitrary code execution. Google awarded a $7,000 bounty for its discovery.
- CVE-2025-2135 – Discovered by researcher Zhenghang Xiao (@Kipreyyy), this vulnerability highlights persistent security concerns within Chrome’s JavaScript processing architecture.
What is Type Confusion?
Type confusion occurs when a program incorrectly treats a memory object as a different type than originally intended, leading to unpredictable behavior, crashes, or malicious code execution.
2. Out-of-Bounds Write in GPU Component (CVE-TBD)
An out-of-bounds write vulnerability in Chrome’s GPU module was also patched.
- This flaw enables attackers to overwrite data beyond allocated memory, potentially leading to system crashes or remote code execution.
- GPU-related vulnerabilities are particularly concerning as they can be exploited to bypass security mechanisms and execute unauthorized commands on a system.
3. Medium-Severity Vulnerabilities Fixed
In addition to the high-risk security flaws, Google also patched two medium-severity issues:
- CVE-2025-2136 – Use-After-Free in Inspector Component
- A use-after-free flaw occurs when a program continues to use memory that has already been deallocated, leading to crashes or possible code execution.
- Reported by Sakana.S, who received a $3,000 bounty.
- CVE-2025-2137 – Out-of-Bounds Read in V8
- This vulnerability allows attackers to read data outside of allocated memory, potentially exposing sensitive information.
- Discovered by zeroxiaobai@, earning a $2,000 bounty.
Why These Vulnerabilities Matter
Even though Google has not confirmed active exploitation of these flaws, the risk of cyberattacks remains high. Attackers often leverage vulnerabilities in widely used software like Chrome for:
✔ Drive-by downloads – Malicious websites can trigger the exploit simply by being visited.
✔ Data theft – Out-of-bounds read vulnerabilities can expose private data.
✔ Malware installation – Exploiting these flaws can allow attackers to install malicious software without user consent.
✔ Remote code execution (RCE) – Attackers gain full control over affected systems.
Given these threats, users and businesses must act immediately by updating Chrome.
How to Update Chrome & Protect Your Device
Although Chrome updates automatically, the patches do not take effect until the browser is restarted. Here’s how to check and apply updates manually:
- Open Google Chrome.
- Click on the three-dot menu (top-right corner).
- Select Help > About Google Chrome.
- Chrome will check for updates and install them automatically.
- Click Relaunch to restart Chrome and apply the updates.
For enterprises managing multiple systems, it’s crucial to enforce update policies to ensure all devices receive the patch promptly.
The Growing Threat Landscape for Browser Exploits
The latest Chrome security update marks the fourth major patch in 2025, highlighting the increasing frequency of browser-based attacks. Cybercriminals continually target web browsers due to their central role in online activities.
✔ JavaScript engines (V8) remain a high-value target for hackers.
✔ GPU vulnerabilities can lead to deep system compromises.
✔ Memory management flaws like use-after-free and out-of-bounds writes are frequently exploited.
This trend underscores the importance of ongoing security monitoring and rapid response to threats.
