Race in Updater in Google Chrome on Mac prior to 151.0.7922.72 allowed a local attacker to perform OS-level privilege escalation via a malicious file. (Chromium security severity: Critical)
AnalysisAI
Local OS-level privilege escalation in Google Chrome's Updater on macOS (versions prior to 151.0.7922.72) allows a local attacker who can plant a malicious file to exploit a race condition and elevate privileges on the host. Google rated the underlying Chromium bug Critical, though the CVSS base score is 7.8 (High) reflecting the local attack vector and required user interaction. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the macOS host and the ability to plant a malicious file that the Google Chrome Updater processes, then to win the CWE-362 race condition timing window during a privileged update operation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (7.8 High) indicates local access (AV:L) with low complexity, no privileges required, but mandatory user interaction (UI:R), and high impact to confidentiality, integrity, and availability - consistent with a local EoP rather than a remote compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local, unprivileged user (or malware already running at user level) plants a crafted malicious file in a location the Chrome Updater processes, then races the privileged update operation to win the timing window between validation and use. Winning the race causes the elevated updater to act on the attacker's file, granting OS-level privileges. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on macOS via the Chrome Stable channel; the fix is documented at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
