Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Requires a pre-compromised renderer foothold (PR:L) and reliable memory-reclamation plus victim navigation (AC:H, UI:R); success escapes the sandbox across a privilege boundary (S:C) with total impact.
Primary rating from Vendor (Chrome).

Use after free in Audio in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome desktop prior to 151.0.7922.72 lets an attacker who has already compromised the renderer process leverage a use-after-free in the Audio component to break out of the sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6 due to scope change, this is a second-stage exploit primitive rather than an initial-access bug; no public exploit has been identified at time of analysis and EPSS is low at 0.29%. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have ALREADY compromised Chrome's renderer process - this is a chained sandbox-escape primitive, not an initial-access vulnerability, and it cannot be triggered against a healthy renderer alone. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and should be read in context. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first lands remote code execution inside Chrome's sandboxed renderer (e.g., via a separate renderer bug), then serves a crafted HTML page that drives the Audio component to trigger the use-after-free and reclaim the freed allocation. By controlling the reused memory across the process boundary, they escalate out of the sandbox to the browser process, converting a contained renderer compromise into full-privilege code execution on the host. … |
| Remediation | Vendor-released patch: Chrome 151.0.7922.72 - update Google Chrome to 151.0.7922.72 or later on Windows, macOS, and Linux and fully relaunch the browser so the new binaries load (Chrome auto-updates but requires a restart to complete). … Detailed patch versions, workarounds, and compensating controls in full report. |
