Use after free in Gamepad in Google Chrome on Windows prior to 149.0.7827.103 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
Articles & Coverage 1
AnalysisAI
Sandbox escape in Google Chrome on Windows prior to 149.0.7827.103 allows remote attackers to exploit a use-after-free flaw in the Gamepad component via a crafted HTML page, requiring only that a victim visit a malicious site. Chromium rates this Critical severity and the CVSS score of 9.6 reflects scope change (sandbox escape) with high impact across confidentiality, integrity, and availability. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Victim must visit an attacker-controlled or compromised web page in a vulnerable Chrome build on Windows (UI:R, user interaction required) - no authentication, no special site permissions, and no non-default configuration are needed, since the Gamepad API is exposed to any origin by default and does not require a prompt to enumerate devices. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All signals point to high real-world risk: CVSS 9.6 with AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H captures network-reachable, low-complexity, unauthenticated exploitation that only needs a user to load a page, and the scope change (S:C) reflects the sandbox escape crossing the renderer trust boundary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious page (or compromises an ad network / watering-hole site) containing JavaScript that manipulates Gamepad API objects to trigger the use-after-free; when a victim on Windows visits the page with a vulnerable Chrome build, the freed memory is reclaimed under attacker control, allowing code execution in the higher-privileged browser process and escape from the renderer sandbox. Chained with a renderer RCE, this yields full code execution on the host at user privilege. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 for Windows - update immediately via the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html and force a relaunch so the new binary loads (Chrome does not apply the fix until the browser is restarted). … Detailed patch versions, workarounds, and compensating controls in full report. |
