Use after free in Dawn in Google Chrome on Mac 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 in Google Chrome on macOS prior to 149.0.7827.103 enables remote attackers to potentially execute arbitrary code by luring a user to a crafted HTML page that exploits a use-after-free in the Dawn WebGPU implementation. The flaw carries a CVSS 8.8 (High) rating and Chromium rates it High severity; no public exploit has been identified at time of analysis, but Chrome browser bugs of this class are historically attractive targets for in-the-wild exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires (1) the victim running Google Chrome on macOS at a version below 149.0.7827.103, (2) the victim visiting an attacker-controlled or compromised HTML page (UI:R - user interaction required), and (3) WebGPU/Dawn being reachable from the rendering context, which it is by default in modern Chrome. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H reflects a classic browser drive-by: network-reachable, low complexity, no privileges, but requires user interaction (visiting a page). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or compromises a website containing a crafted HTML page with JavaScript that issues a specific sequence of WebGPU calls to Dawn, freeing a GPU-related object and then reallocating attacker-controlled data into the freed slot before reuse. When a macOS Chrome user on a vulnerable build visits the page (via phishing link, malvertising, or watering hole), the use-after-free triggers heap corruption inside the renderer process, giving the attacker an initial code execution primitive that would typically be chained with a sandbox escape for full system compromise. … |
| Remediation | Vendor-released patch: update Google Chrome on macOS to 149.0.7827.103 or later via the Stable channel update referenced at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html; Chrome will auto-update on restart, so administrators should force-relaunch browsers across the fleet to ensure the fix is loaded. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
