Please refer to the following to understand the unexpected behaviors when using new KSPs.

  • Trend Micro adopts the live-patching mechanism from the Linux kernel to solve the BHI issue. Our solution may fail patching the Linux kernel if it has been patched by other patches or modules previously.
  • For existing XES agents (before the July 2024 Release) running with the new KSPs, the tmhook driver can not be unloaded properly. However, this behavior does not affect the system nor break any of our security features. Trend Micro plans to resolve this behavior in Trend Vision One Endpoint Security agent in the July 2024 Release.
