Chrome Update Patches Exploited XML Zero-Day, Eighth This Year

Google’s latest Chrome update patches a critical zero-day vulnerability that has already been exploited in the wild. This is just one of nine vulnerabilities addressed in the patch, which also includes six high-severity bugs and two medium-severity issues. The zero-day exploit, tracked as CVE-2026-125350, affects the browser’s XML component and is described as a use-after-free vulnerability.

The Chrome update comes after another busy month for the browser’s security team, with seven other zero-days exploited this year alone. In fact, 2026 has seen an alarming number of high-severity vulnerabilities in popular software like Chrome, putting users at risk of cyber attacks. To put this into perspective, Google’s internal research discovered most of the recent flaws, including six out of the nine patched issues.

For those unfamiliar with technical jargon, a use-after-free vulnerability occurs when a program tries to access memory that has already been freed or deallocated. This can allow an attacker to execute malicious code on the target system. In this case, the XML component of Chrome is vulnerable to such exploitation. Although Google hasn’t shared any details about the attacks, experts are concerned that users may have fallen victim to these exploits without even realizing it.

One researcher reported the issue to Google on November 6, prompting an expedited patch release. The vulnerability has not yet been added to the CISA’s Known Exploited Vulnerabilities (KEV) catalog, which suggests that attacks using this exploit are still relatively rare. Nevertheless, users are advised to update their Chrome browsers as soon as possible to ensure protection against any potential threats.

The patches included in Chrome 157 updates address vulnerabilities across multiple components, including WebGL, FileSystem, Compositing, GPU, V8, and XML. The two medium-severity bugs fixed in the GPU component relate to uninitialized resource issues. To stay safe online, users should keep their browsers up-to-date with the latest security patches.

As the frequency of high-severity vulnerabilities continues to rise, it’s essential for individuals and organizations to prioritize cybersecurity best practices, such as keeping software updated and using robust antivirus solutions. While this latest patch is a welcome development, it highlights the ongoing need for vigilance in protecting against emerging threats. By staying informed about the latest security updates and following basic precautions, users can minimize their risk of falling victim to cyber attacks.
