Severity by source
AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Requires a pre-compromised renderer (PR:L) and user interaction (UI:R) at high complexity (AC:H); escaping the renderer sandbox into the browser process is a scope change (S:C) with high C/I/A impact.

Insufficient validation of untrusted input in Speech in Google Chrome on Android prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Privilege escalation in Google Chrome for Android before 150.0.7871.47 lets an attacker who has already compromised the renderer process break out further by feeding a crafted HTML page into the Speech component, which fails to validate untrusted input (CWE-20). Google rated it Medium severity; a fix has shipped in the Stable channel, EPSS is low (0.21%, 11th percentile), and there is no public exploit identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process on Android - this is not a standalone remote bug but the second stage of a chain. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals point to a real but conditional issue rather than a mass-exploitation emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first lands a separate renderer-compromise exploit (for example via a malicious ad or web page that exploits an unrelated Chrome renderer bug), then serves a crafted HTML page whose Speech-related interactions send malformed input across the renderer-browser boundary. Because the Speech component under-validates that input, the attacker escalates out of the renderer sandbox toward higher-privilege browser-process context on the Android device. … |
| Remediation | Vendor-released patch: update Google Chrome for Android to 150.0.7871.47 or later, per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); on Android this arrives through Google Play, so ensure automatic app updates are enabled and force-update managed fleets via MDM. … Detailed patch versions, workarounds, and compensating controls in full report. |
