The CVE-2026-2441 vulnerability is a high-severity use-after-free flaw found in the CSS component of Google Chrome versions prior to 145.0.7632.75 . A use-after-free occurs when a program continues to reference memory after it has been freed, which can lead to program crashes or, in this case, allow an attacker to execute arbitrary code . This specific bug in the CSS font value processor could be triggered by convincing a user to visit a specially crafted HTML page . Once triggered, the flaw allows a remote attacker to execute arbitrary code, although it is contained within Chrome’s sandbox . Discovered by researcher Shaheen Fazim on February 11, 2026, Google confirmed that an exploit for this vulnerability exists in the wild, making it the first actively exploited Chrome zero-day of 2026 .
