Severity by source
Sources disagree (Medium–Critical)AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Local malicious-file delivery gives AV:L; victim must open the file so UI:R; no privileges needed (PR:N); OS-level privilege escalation yields C:H/I:H/A:H.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Use after free in Tracing in Google Chrome on Windows prior to 151.0.7922.72 allowed a local attacker to perform OS-level privilege escalation via a malicious file. (Chromium security severity: Medium)
AnalysisAI
Local privilege escalation in Google Chrome for Windows before 151.0.7922.72 stems from a use-after-free in the Tracing component (CWE-416), letting a local attacker who lures a user into opening a malicious file execute code that escalates to OS-level privileges. Chromium rates the security severity as Medium, but the assigned CVSS 3.1 score is 7.8 (High) reflecting full confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local delivery of a specially crafted malicious file to the target and requires the victim user to open/process that file in Google Chrome on Windows (CVSS UI:R), triggering the use-after-free in the Tracing component; no prior authentication or privileges are needed (PR:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 7.8) describes a local, low-complexity attack needing no prior privileges but requiring user interaction, with high impact to all three security properties - consistent with the description's 'local attacker via a malicious file.' Note the discrepancy between Chromium's own 'Medium' severity rating and the 7.8 'High' CVSS: Chromium's grading reflects the browser-security model, while the CVSS reflects OS-level impact once triggered, so both are defensible. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious file and uses social engineering (phishing, malicious download) to get a local user to open it in an unpatched Chrome on Windows; opening the file triggers the use-after-free in the Tracing component, corrupting heap memory. The attacker leverages this to execute code that escalates to OS-level privileges on the machine. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on Windows; Chrome typically auto-updates, but administrators should force the update and relaunch the browser to apply it, verifying via chrome://settings/help and consulting the 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. |
