Google has fixed three high-severity Chrome flaws that could enable remote exploitation.
Google has released a security update for its Chrome browser that addresses three high-severity vulnerabilities, which could pose risk to users.
One of the vulnerabilities, CVE-2026-3061, allows “… a remote attacker to perform an out-of-bounds memory read via a crafted HTML page,” said NIST in its advisory.
The security update addresses three High severity vulnerabilities — CVE-2026-3061, CVE-2026-3062, and CVE-2026-3063 — spanning Chrome’s Media component, the Tint WebGPU shader compiler, and Chrome DevTools.
Two of the three flaws involve out-of-bounds memory access, a vulnerability class commonly associated with remote code execution (RCE), memory disclosure, and sandbox escape chains when paired with additional weaknesses.
CVE-2026-3061 is an out-of-bounds read vulnerability in Chrome’s Media component.
Out-of-bounds reads occur when software accesses memory outside the intended buffer, potentially exposing sensitive data or destabilizing the application.
In a browser context, media processing is frequently exposed to untrusted input delivered through web pages, advertisements, or embedded content.
An attacker could craft malicious media files designed to trigger the flaw when rendered by the browser, creating the potential for drive-by exploitation — where a user is compromised simply by visiting a malicious or compromised website.
While an out-of-bounds read alone does not automatically grant code execution, it can leak memory contents or serve as a building block within a broader exploit chain.
This vulnerability affects Tint, Chrome’s WebGPU shader compiler, and involves both out-of-bounds read and out-of-bounds write conditions.
Out-of-bounds writes can lead to memory corruption, potentially allowing attackers to manipulate program control flow.
In practical terms, successful exploitation could enable arbitrary code execution within the browser’s renderer process.
As WebGPU adoption increases to support high-performance graphics, AI workloads, and advanced browser-based applications, components like Tint expand Chrome’s attack surface.
Graphics and shader compilers process complex instructions, and vulnerabilities in these pipelines can provide attackers with a powerful foothold inside the browser sandbox.
The third vulnerability, CVE-2026-3063, involves an inappropriate implementation in Chrome DevTools.
Although implementation flaws in developer tooling may not carry the same immediate impact as memory corruption bugs, they can still introduce security risks.
Under certain conditions, such weaknesses could enable cross-origin data exposure, privilege misuse, or bypasses of browser-enforced security controls.
Given that DevTools interacts closely with page content and debugging interfaces, improper boundary enforcement can undermine core browser security assumptions.
At the time of publication, Google has not indicated that any of the three vulnerabilities are being actively exploited in the wild.
Modern browsers function as full-featured application platforms, which means they can present meaningful risk if vulnerabilities are left unaddressed.
The following steps provide measures security teams can take to strengthen protections against browser-based threats.
Collectively, these measures help limit blast radius and build resilience against browser-based threats.
Although there is no evidence of active exploitation, the High severity ratings and underlying memory safety risks justify prioritization within enterprise risk management programs.
For security teams, the browser is a key control layer, acting as the primary gateway to SaaS applications, cloud environments, and sensitive corporate data.
As browser functionality continues to evolve — including support for AI-driven applications and GPU-accelerated workloads — maintaining strong patch governance and layered security controls will be essential to managing expanding attack surfaces.
These realities reinforce why organizations are adopting zero-trust solutions to better control access and contain risk at the browser and user level.
