Use after free in Bluetooth in Google Chrome prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to execute arbitrary code outside the sandbox via a crafted Chrome extension. (Chromium security severity: High)
AnalysisAI
Use-after-free in the Bluetooth component of Google Chrome prior to version 152.0.7977.65 enables remote attackers to execute arbitrary code outside the browser sandbox. Exploitation requires the attacker to socially engineer a victim into installing or triggering a crafted Chrome extension, after which the memory corruption in the Bluetooth subsystem is leveraged to escape Chrome's sandbox and achieve code execution at the OS level. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to install or interact with a crafted Chrome extension through social engineering - this is the explicit attack delivery mechanism stated in the description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects high severity, but the S:U (no scope change) metric appears inconsistent with the description, which explicitly states execution occurs 'outside the sandbox' - a textbook scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious Chrome extension that triggers the use-after-free in Chrome's Bluetooth subsystem when activated. The attacker distributes the extension via a phishing campaign, a fake Chrome Web Store listing, or a compromised developer account, socially engineering the target into installing it. … |
| Remediation | Vendor-released patch: 152.0.7977.65. … Detailed patch versions, workarounds, and compensating controls in full report. |
