CVE-2026-3536 is an integer overflow vulnerability identified in the ANGLE graphics engine component of Google Chrome prior to version 145.0.7632.159. ANGLE is responsible for translating OpenGL ES calls to DirectX or Vulkan, playing a critical role in rendering web graphics. The integer overflow occurs when processing certain crafted HTML content, leading to out-of-bounds memory access. This memory corruption can be exploited by a remote attacker to execute arbitrary code within the context of the browser or cause denial of service through crashes. The vulnerability requires no privileges and no authentication but does require user interaction, such as visiting a malicious webpage. The CVSS v3.1 base score is 8.8, reflecting high severity with network attack vector, low attack complexity, no privileges required, user interaction needed, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the critical nature and ease of exploitation make this a significant threat. The vulnerability is classified under CWE-190 (Integer Overflow or Wraparound), a common source of memory corruption issues. Google has released a patched version 145.0.7632.159 to address this flaw, but no direct patch links are provided in the data. Organizations using affected Chrome versions should prioritize updating to mitigate risk.

The impact of CVE-2026-3536 is substantial due to the potential for remote code execution, which could allow attackers to take full control of the victim's browser environment. This can lead to data theft, session hijacking, installation of malware, or pivoting to internal networks. The vulnerability compromises confidentiality by exposing sensitive information, integrity by allowing unauthorized code execution or data manipulation, and availability by enabling denial of service through crashes. Since Chrome is a widely used browser globally, the scope of affected systems is vast, including enterprise environments, government agencies, and individual users. The requirement for user interaction (visiting a malicious webpage) slightly limits automated exploitation but does not significantly reduce risk given common web browsing habits. The absence of known exploits in the wild currently provides a window for proactive defense, but the critical severity score indicates attackers may develop exploits rapidly. Organizations failing to patch promptly face increased risk of targeted attacks and widespread exploitation.

1. Immediately update Google Chrome to version 145.0.7632.159 or later to apply the official patch addressing the integer overflow in ANGLE. 2. Employ network security controls such as web filtering and intrusion prevention systems to block access to known malicious websites and suspicious HTML content. 3. Educate users about the risks of visiting untrusted websites and the importance of prompt browser updates. 4. Implement endpoint protection solutions capable of detecting anomalous browser behavior or exploitation attempts. 5. Use browser security features like sandboxing and strict content security policies to limit the impact of potential exploits. 6. Monitor security advisories and threat intelligence feeds for emerging exploit reports related to this vulnerability. 7. For high-risk environments, consider restricting browser usage or deploying hardened browser configurations until patches are fully deployed. 8. Conduct regular vulnerability assessments and penetration testing to verify the effectiveness of mitigation measures.
