CVE-2026-106393 is a use-after-free vulnerability in the Storage subsystem of Google Chrome versions before 155.0.8059.39. Exploitation requires that the attacker has already compromised the renderer process, after which they can execute arbitrary code outside the sandbox environment via a specially crafted HTML page. This vulnerability was publicly disclosed and fixed in a stable update by Google.
Potential Impact
