Local privilege escalation via Updater use-after-free
Published Jul 30, 2026 · Updated Jul 30, 2026
Use after free in Google Chrome's Updater before 151.0.7922.72 on Mac allows local users to gain elevated privileges via network traffic. The restricted Chromium issue identifies the Updater lifecycle fault but does not disclose which object is freed or how malicious network traffic causes its later reuse. Exploitation requires local execution on macOS and can raise the attacker's privileges; no Windows or Linux exposure is reported.
