TmComm.sys 1.5.0.1052 in the Trend Micro Anti-Rootkit Common Module (RCM), with the VsapiNI.sys 3.320.0.1003 scan engine, as used in Trend Micro PC-cillin Internet Security 2007, Antivirus 2007, Anti-Spyware for SMB 3.2 SP1, Anti-Spyware for Consumer 3.5, Anti-Spyware for Enterprise 3.0 SP2, Client / Server / Messaging Security for SMB 3.5, Damage Cleanup Services 3.2, and possibly other products, assigns Everyone write permission for the \\.\TmComm DOS device interface, which allows local users to access privileged IOCTLs and execute arbitrary code or overwrite arbitrary memory in the kernel context.

Security readout for executives and security teams

This is a local privilege escalation flaw in older Trend Micro security software. A normal Windows user could abuse an overly permissive Trend Micro kernel device interface to run code with kernel privileges or overwrite kernel memory. It matters mainly where the listed 2007-era Trend Micro products or shared components remain installed. Exposure is limited to systems running the affected Trend Micro products or possibly other products using the vulnerable RCM/TmComm.sys component. Because the products are old, the main concern is legacy endpoints, unmanaged servers, archived images, or embedded operational systems with stale antivirus installations. High priority for any legacy Windows environment still running the affected Trend Micro components. This is not a remote internet-facing bug, but it can turn a low-privileged local foothold into kernel-level control. If the software is no longer present, business urgency is low. Mitigation focus: Inventory endpoints for the listed Trend Micro products and shared RCM components.; Check Trend Micro guidance for supported updates, replacements, or retirement instructions.; Remove unsupported 2007-era Trend Micro products from active systems..
