CVE-2026-121229: Memory corruption in ANGLE, which could allow a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page.

ANGLE is Chrome’s graphics translation layer. A buffer overflow occurs when a program puts more data into an area of memory than it can hold, overwriting data in adjoining memory. An attacker can exploit this to make the vulnerable process run malicious code.

Chrome vulnerabilities that enable remote code execution outside the browser sandbox are particularly valuable to attackers because they can turn a visit to a malicious or compromised website into direct code running on the underlying operating system, often without requiring additional exploitation steps.

CVE-2026-121035: Use-after-free in Prerender.

Chrome’s Prerender component helps pages open faster by loading and preparing a page in the background before you navigate to it. If you then visit that page, Chrome can display the prepared version almost instantly instead of loading it from scratch.

This goes beyond just downloading content: Chrome also starts rendering the page and running its JavaScript.

A use-after-free vulnerability occurs when a program attempts to access a memory location after it has been freed. That can cause crashes or, in some cases, allow an attacker to run their own code.

CVE-2026-121156: Buffer overflow in Dawn.

Dawn powers WebGPU in Chrome, allowing websites to use a device’s graphics processor for rendering and computational tasks. It checks and translates WebGPU instructions into commands that the device’s underlying graphics system can understand.

A buffer overflow occurs when a program writes more data to a block of memory than it can hold. This can cause a crash or, in some cases, allow an attacker to run code.

After the update, the version should be 159.0 or later

Technical details

These Chrome and Firefox updates address a familiar problem: browser code mishandling memory while processing web content. Both releases fix use-after-free vulnerabilities, including flaws in page layout, JavaScript processing, and SVG graphics.

A use-after-free vulnerability occurs when a program attempts to access a memory location after it has been freed. That can cause crashes or, in some cases, allow an attacker to run their own code.

There’s another connection between these updates: both Google and Mozilla credit OpenAI Codex Security with finding bugs fixed in these releases. AI can help security teams examine browser code for weaknesses, alongside human code reviews and automated tests that check how software handles unexpected inputs.

Mozilla’s collaboration with Anthropic shows how AI-discovered findings can lead to fixes: researchers validated vulnerabilities before reporting them, giving Mozilla’s team reproducible bugs to investigate, repair, and deliver to users.

Google Fixes 10 Chrome Vulnerabilities, Including Memory Corruption Flaw Found With Claude AI

Google released a Chrome Stable security update fixing 10 vulnerabilities across Windows, Mac, and Linux, including a high-severity DOM memory corruption flaw reported by Xinyang Ge of Anthropic with Claude AI.

The update also addresses one critical, six high-severity, and three medium-severity vulnerabilities. Google announced the update on October 15, 2026.

Google is rolling out Chrome versions 155.0.8059.84/.85 for Windows and Mac, and version 155.0.8059.84 for Linux over the coming days and weeks. Users should install the update when it becomes available and check Chrome’s About page to prompt an update check.

The most serious issue is CVE-2026-110922, a critical use-after-free flaw in Chrome’s Prerender feature. Google credits Xinyang Ge with reporting it on October 2.

A use-after-free bug occurs when software tries to use memory after it has been released. Depending on how an attacker can reach the flaw, this type of error may cause a crash or allow memory corruption. Google has not published further technical details and has not said the issue is being exploited.

CVE-2026-110913 is a high-severity memory corruption flaw in Chrome’s DOM, the browser system that represents and manages the structure of web pages.

Google Fixes 10 Chrome Vulnerabilities

Ge reported the bug on September 29, with Claude’s assistance. Google’s release note does not explain how the issue was found, whether Claude identified the flaw or helped with analysis, or what steps were involved. It does, however, publicly credit the AI’s assistance in the report.

The other high-severity fixes affect V8, Chrome’s JavaScript engine, as well as Core and SVG. They include two additional use-after-free flaws in V8, CVE-2026-110919 and CVE-2026-110921, and memory corruption issues CVE-2026-110918, CVE-2026-110917, and CVE-2026-110920. The reports came from Ge, Google, and researcher C0rk1.

The three medium-severity bugs involve improper input validation in Desktop, a use-after-free issue in Compositing, and memory corruption in Workers.

Google credited its own researchers with reporting these flaws. Together, the list shows that this release addresses problems in separate browser components rather than a single feature or subsystem.

Google says detailed bug information may remain restricted until most users have installed the fixes. This can limit what researchers and users can learn about the vulnerabilities while the update is spreading.

The company also said it uses tools such as AddressSanitizer, MemorySanitizer, libFuzzer, and AFL to find security bugs during development.

Chrome updates are delivered gradually, so users may not receive the new version at the same time. Check the browser’s About Google Chrome page and restart it if prompted to complete installation. Organizations should follow their normal browser update process and confirm that managed devices receive the fixed release.

This update follows other recent Chrome security coverage, including Google’s earlier report on a large Chrome vulnerability update and coverage of multiple Chrome flaws. Google’s Stable Channel announcement and Chrome Security page provide the primary release information.

The first is tracked as CVE-2026-110152, a buffer overflow in ANGLE in Google Chrome on Android. It could allow a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page.

ANGLE is Chrome’s graphics-translation layer. A buffer overflow occurs when a program puts more data into an area of memory than it can hold, overwriting data in adjoining memory. An attacker can exploit this to make the vulnerable process run malicious code.

Chrome vulnerabilities that enable remote code execution outside the browser sandbox are particularly valuable to attackers because they can turn a visit to a malicious or compromised website into direct code running on the underlying operating system, often without requiring additional exploitation steps.

Then I spotted two use-after-free vulnerabilities in the PDF component. CVE-2026-110136, rated Critical, could allow a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. CVE-2026-110147, rated High, could allow an attacker to execute arbitrary code inside the sandbox via a crafted HTML page.

A use-after-free vulnerability occurs when a program attempts to access a memory location after it has been freed. That can cause crashes or, in some cases, allow an attacker to run their own code.

Inside the sandbox means the malicious code would run in a restricted, sealed-off environment designed to limit access to the rest of your device. That limits what the attacker can do as it constrains them to the browser, lowering the impact compared with code running outside the sandbox. However, attackers often chain multiple vulnerabilities together to escape the sandbox and achieve a more serious compromise. So, the phrase describes an important security limitation, but it does not mean the vulnerability is harmless.
