Use after free in Core in Google Chrome on on Windows prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Use-after-free in Google Chrome's Core component on Windows prior to 153.0.8010.36 enables a renderer-compromised attacker to escape the browser sandbox and execute arbitrary code on the host OS. The vulnerability is platform-specific to Windows and functions as the second stage of a chained exploit: an attacker must first achieve renderer-level compromise before triggering this UAF to pivot into the privileged browser process. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two explicit preconditions: first, the attacker must have already achieved code execution within the Chrome renderer process - this is stated in the CVE description as 'a remote attacker who had compromised the renderer process' and is the binding limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.3 (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) accurately captures the dual-condition nature of this vulnerability - catastrophic post-exploitation impact moderated by high attack complexity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: Chrome 153.0.8010.36 for Windows. … Detailed patch versions, workarounds, and compensating controls in full report. |
