AI Analysis
Technical Summary
CVE-2026-15902 is a use-after-free vulnerability in the Cast feature of Google Chrome before version 150.0.7871.128. Exploitation requires a user interaction (UI:R) and can be triggered remotely via a crafted HTML page. Successful exploitation could lead to arbitrary code execution inside the browser sandbox, impacting confidentiality, integrity, and availability. The vulnerability is tracked as CWE-416 (Use After Free) and has a CVSS v3.1 vector indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker can remotely execute arbitrary code inside the sandboxed environment of the affected Chrome browser by convincing a user to visit a maliciously crafted HTML page. This can lead to full compromise of the browser process within the sandbox, potentially allowing data theft, manipulation, or denial of service within the sandbox context.
Mitigation Recommendations
A fix is available in Google Chrome version 150.0.7871.128 and later. Users and administrators should update to this version or later to remediate the vulnerability. Since this is not a cloud service, patching the client software is required. There are no vendor advisories indicating that no action is required or that the issue is already mitigated without patching.
