CVE-2026-17891 is a use-after-free vulnerability in the ANGLE graphics engine within Google Chrome on Android platforms before version 151.0.7922.72. An attacker who has compromised the renderer process can exploit this flaw to potentially perform a sandbox escape, increasing the level of control beyond the renderer sandbox. The vulnerability is identified as CWE-416 (Use After Free). There is no CVSS score provided, and no known exploits in the wild have been reported. No patch links or vendor advisory details are available in the provided data.

Successful exploitation could allow an attacker with control over the renderer process to escape the sandbox, potentially leading to further compromise of the device beyond the renderer's restricted environment. This elevates the attacker's privileges and could facilitate additional malicious actions.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should update Google Chrome on Android to version 151.0.7922.72 or later once available. Until then, limiting exposure to untrusted web content and following best practices for app security is advisable.
