CVE-2018-6236
Estado: ModificadaAlta (7)—
A Time-of-Check Time-of-Use privilege escalation vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within processing of IOCTL 0x222813 by the tmusa driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
