Use after free in Receiver in Google Chrome prior to 153.0.8010.36 allowed an adjacent attacker to execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: High)
AnalysisAI
Use-after-free in Chrome's Receiver component allows an adjacent, unauthenticated attacker to execute arbitrary code outside the renderer sandbox via crafted network traffic, affecting all Chrome versions prior to 153.0.8010.36. The scope change in the CVSS vector confirms this is a full sandbox escape - successful exploitation yields OS-level code execution on the victim machine without requiring any user interaction. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same adjacent network segment as the target - same LAN, shared Wi-Fi network, or subnet - since the vulnerability is exposed via crafted network traffic rather than a web page or downloaded file. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Despite the high CVSS impact metrics (C:H/I:H/A:H with scope change), the real-world risk is meaningfully constrained by two factors: AV:A (adjacent network only) and AC:H (high attack complexity requiring precise heap-state conditions). … 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: 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of Chrome deployments across the organization and identify all systems running versions prior to 153.0.8010.36, prioritizing endpoints with network connectivity and access to sensitive data. …
