Use-after-free in Chrome Input sandbox escape on Android

IdentifiersCVE-2026-8513CWE-416· Use After Free

CVE-2026-8513 is a critical use-after-free vulnerability in the Input component of Google Chrome on Android prior to version 148.0.7778.168. According to the provided advisory text, the flaw can be triggered via a crafted HTML page and is exploitable by a remote attacker who has already compromised the renderer process. The vulnerability is described as enabling a potential sandbox escape, indicating that improper object lifetime handling in the Input component may allow access to freed memory and subsequent corruption or control-flow impact across the browser security boundary.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow an attacker who already achieved renderer-process compromise to escape Chrome's sandbox on Android. This can enable execution beyond the renderer's intended isolation boundary, potentially leading to broader access to browser or system resources than the renderer should have, and materially increasing the severity of an initial renderer compromise.

Mitigation

If you can’t patch tonight, do this now.

Apply the vendor update as soon as possible. Until patching is complete, reduce exposure by limiting use of untrusted web content in Chrome on Android, and prioritize patching devices where renderer compromise would present elevated risk. No specific workaround beyond updating is provided in the supplied content.

Remediation

Patch, then assume compromise.

Update Google Chrome on Android to version 148.0.7778.168 or later. The provided content states that versions prior to 148.0.7778.168 are affected.
