The CVE-2026-2441 vulnerability is classified as a high-severity use-after-free issue in Google Chrome. This vulnerability allows remote attackers to execute arbitrary code inside a sandboxed environment via a crafted HTML page, which poses significant risks to users and organizations. With a CVSS score of 8.8, this vulnerability is critical and must be addressed immediately.
The risk to organizations includes potential unauthorized access and control over affected systems, leading to data breaches and loss of sensitive information. Given the widespread use of Google Chrome, the impact of this vulnerability could be extensive. Attackers may leverage this vulnerability to exploit applications and systems relying on the Chromium engine.
With known exploits available, security teams must prioritize patching this vulnerability. The urgency for defenders is critical, as failing to remediate could lead to significant operational and reputational damage.
Organizations should ensure that their installations of Google Chrome are updated to version 145.0.7632.75 or later to mitigate this vulnerability effectively.
Vulnerability Details
The official description of CVE-2026-2441 states: 'Use after free in CSS in Google Chrome prior to 145.0.7632.75 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.' This vulnerability falls under the CWE classification of CWE-416.
Published on February 13, 2026, this vulnerability has been assigned a CVSS score of 8.8, indicating a high severity level. The attack vector is network-based, with low complexity and no privileges required, yet it necessitates user interaction. The impact on confidentiality, integrity, and availability is rated as high.
Technical Analysis
The root cause of this vulnerability stems from improper management of memory in the CSS rendering process. Specifically, the use-after-free condition occurs when a memory location is accessed after it has been freed, allowing attackers to potentially execute arbitrary code.
This vulnerability can be exploited through network interactions, such as by visiting a malicious web page. The attack complexity is low, meaning that an attacker does not need advanced skills to exploit it. User interaction is required, as the victim must visit a crafted HTML page to trigger the vulnerability.
The impacts of this vulnerability are significant, affecting confidentiality, integrity, and availability. Successful exploitation could lead to complete control over the affected environment.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2026-2441 is substantial, given the popularity of Google Chrome. Organizations using this browser for everyday operations face potential exposure to attacks that could lead to unauthorized data access, loss of sensitive information, and a compromised network.
This vulnerability highlights the importance of maintaining up-to-date software across all endpoints. The blast radius could be extensive, affecting not only individual users but also organizations with interconnected systems relying on the Chromium engine.
The urgency for addressing this vulnerability is high, as it is actively exploited. Organizations should prioritize this vulnerability in their patch management processes due to its potential impact and exploitability.
