Use after free in FullScreen in Google Chrome on Windows prior to 149.0.7827.103 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Heap corruption via use-after-free in Google Chrome's FullScreen component on Windows prior to 149.0.7827.103 enables remote attackers to potentially achieve code execution when a victim visits a malicious HTML page. Chromium rates this High severity and a vendor patch is available, though no public exploit has been identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Victim must be running Chrome on Windows at a version below 149.0.7827.103 and must visit (or be redirected to) attacker-controlled HTML content - UI:R in the CVSS vector confirms user interaction is required, typically a navigation or click. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed but lean toward prioritized patching: CVSS 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates remote, unauthenticated, low-complexity exploitation requiring a single user click/navigation, with high impact on confidentiality, integrity, and availability within the renderer's scope. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious HTML page that scripts an abusive Fullscreen API interaction sequence to trigger the use-after-free in Chrome's FullScreen code path. The victim is lured via phishing, malvertising, or a watering-hole compromise and clicks/navigates to the page, satisfying the UI:R requirement; the dangling pointer is dereferenced over attacker-controlled heap state, yielding renderer-process memory corruption that can be shaped into code execution within the sandbox. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 for Windows - update via the built-in updater (chrome://settings/help) or push through enterprise management (Chrome Browser Cloud Management, Group Policy, or Intune) and restart the browser to apply. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all Windows systems running Chrome versions prior to 149.0.7827.103 using endpoint detection and response (EDR) or mobile device management (MDM) tools; prioritize systems with sensitive data access. …
