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.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
