Use after free in Updater in Google Chrome on Mac prior to 150.0.7871.47 allowed a local attacker to perform privilege escalation via a malicious file. (Chromium security severity: High)
AnalysisAI
Local privilege escalation in Google Chrome's Updater component on macOS versions prior to 150.0.7871.47 lets an attacker abuse a use-after-free (CWE-416) via a malicious file to gain the elevated privileges under which the updater runs. Google rates the Chromium severity as High, and the CVSS 3.1 base score is 7.8; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to a macOS host running Chrome prior to 150.0.7871.47 plus user interaction (CVSS UI:R): the attacker must place a malicious file and have the Chrome Updater component process it to trigger the use-after-free. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are internally consistent and point to a genuine but non-urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker who already has a foothold on a Mac (for example a standard user account or malware running with limited rights) plants a specially crafted malicious file and induces the Chrome Updater to process it, triggering the use-after-free while the updater runs with elevated privileges. Successful memory corruption lets the attacker escalate from limited local access to the updater's higher privilege level. … |
| Remediation | Vendor-released patch: update Google Chrome on macOS to 150.0.7871.47 or later, as published in Google's Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); Chrome's own auto-updater will normally deliver this, and users can force it via chrome://settings/help followed by a relaunch. … Detailed patch versions, workarounds, and compensating controls in full report. |
