Use after free in DOM in Google Chrome prior to 151.0.7922.173 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Use-after-free in Google Chrome's DOM implementation prior to 151.0.7922.173 enables remote unauthenticated attackers to execute arbitrary code inside the Chrome sandbox by luring a user to a crafted HTML page. The CVSS score of 8.8 reflects high confidentiality, integrity, and availability impact, though execution is constrained within the Chromium sandbox, limiting the blast radius without a secondary escape primitive. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a user running an affected version of Google Chrome (prior to 151.0.7922.173) to visit an attacker-controlled or compromised webpage containing a crafted HTML payload (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates low-complexity network exploitation requiring only user interaction - a realistic bar given that phishing or malvertising can reliably drive user visits to attacker-controlled pages. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that manipulates DOM object allocation and deallocation sequences to trigger the use-after-free condition in Chrome's DOM engine. A targeted user is directed to this page via phishing, malvertising, or a compromised website, and upon rendering, the attacker achieves arbitrary code execution within the Chrome renderer sandbox. … |
| Remediation | Update Google Chrome to version 151.0.7922.173 or later; this is the vendor-confirmed fixed release, documented at http://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0404570826.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
