Use after free in Updater in Google Chrome on Windows prior to 150.0.7871.47 allowed a local attacker to perform OS-level privilege escalation via a malicious file. (Chromium security severity: High)
AnalysisAI
Local OS-level privilege escalation in Google Chrome on Windows (versions prior to 150.0.7871.47) arises from a use-after-free in the Chrome Updater component, letting a local attacker who can plant a malicious file on the system elevate to higher OS privileges. Google rates the Chromium severity as High and has released a fixed Stable channel build; there is no public exploit identified and it is not listed in CISA KEV. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the Windows host and the ability to place a malicious file that the privileged Chrome Updater component processes, plus user interaction (CVSS UI:R) to trigger the use-after-free; the vulnerable Updater must be a version prior to 150.0.7871.47. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals broadly agree this is a real but not urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local, low-privilege user on a shared Windows workstation plants a specially crafted malicious file and induces the required user interaction, triggering the use-after-free in the privileged Chrome Updater as it processes the file. The corrupted, higher-privileged Updater execution is steered to run attacker-controlled code, elevating from a standard account to OS-level privileges. … |
| Remediation | Vendor-released patch: upgrade Google Chrome to 150.0.7871.47 or later on Windows via the Stable channel; the primary fix is to allow Chrome's auto-update to apply the patched build and relaunch the browser to complete installation, or push the update through enterprise management (Google Update policies / MSI). … Detailed patch versions, workarounds, and compensating controls in full report. |
