Use after free in Ozone in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox escape in Google Chrome desktop before 151.0.7922.72 stems from a use-after-free in the Ozone platform abstraction layer, letting a remote attacker who lures a victim to a crafted HTML page break out of the renderer sandbox and gain broader host access. Rated Critical by Chromium with CVSS 9.6 and a scope-changed vector, though exploitation currently shows as none in CISA SSVC and EPSS is low (0.31%). …

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 desktop build prior to 151.0.7922.72 (UI:R user interaction - the user must visit or open the malicious page). … 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:C/C:H/I:H/A:H, 9.6) reflects a network-reachable, low-complexity, unauthenticated bug that requires user interaction (visiting a page) and crosses a security scope boundary (sandbox escape) - consistent with the Critical rating and 'total' technical impact in SSVC. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or injects a crafted HTML page and lures a victim to open it in a vulnerable Chrome build; when rendered, the page triggers the Ozone use-after-free to corrupt browser-process memory and escape the renderer sandbox. With AC:L and UI:R, a single click on a link or a malvertising redirect is sufficient, and success grants the attacker code execution outside the sandbox. … |
| Remediation | Vendor-released patch: Chrome 151.0.7922.72 - upgrade to this build or later on all desktop endpoints per the Stable channel advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
