Use after free in DOM in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
Articles & Coverage 1
AnalysisAI
Remote code execution in Google Chrome desktop versions prior to 151.0.7922.72 arises from a use-after-free in the DOM implementation, letting a remote attacker who lures a victim to a crafted HTML page run arbitrary code within the renderer sandbox. The flaw was reported internally by the Chrome team, rated High by Chromium, and carries CVSS 8.8; there is no public exploit identified at time of analysis and EPSS is low at 0.35% (28th percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-controlled HTML in a vulnerable Chrome build (before 151.0.7922.72) - user interaction (UI:R) in the form of visiting or being redirected to a malicious/compromised page is mandatory, so this is not a zero-click drive-by against a passive target. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 8.8 High) indicates a network-reachable, low-complexity, unauthenticated attack that requires user interaction (visiting a malicious page) and does not cross a privilege/scope boundary - consistent with the description's note that code runs 'inside a sandbox.' This is a meaningful contrast: the raw score is high, but Scope:Unchanged plus sandboxed execution means a single bug here does not by itself yield host takeover without a chained sandbox escape. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or compromises a web page containing crafted HTML/JavaScript that manipulates DOM objects to trigger the use-after-free, then delivers it via a phishing link, malvertising, or a watering-hole site. When a victim running a pre-151.0.7922.72 Chrome build visits the page (the required user interaction), the dangling pointer is exploited to gain code execution inside the renderer sandbox. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on all desktop platforms per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html); restart the browser to complete the update since Chrome staged updates do not take effect until relaunch. … Detailed patch versions, workarounds, and compensating controls in full report. |
