CVE-2025-13636 is a low-severity UI spoofing vulnerability in the Split View component of Google Chrome. In Chrome versions prior to 143.0.7499.41, an inappropriate implementation in Split View allowed a remote attacker to leverage a crafted domain name and induce a user to perform specific user-interface gestures, resulting in misleading or spoofed browser UI presentation. The issue is described as an implementation flaw rather than a memory-safety bug, and its effect is to make attacker-controlled content appear more trustworthy or visually confusable with legitimate browser or site context.
