Known issues in the

Linux

agent

* On some

Linux

devices with memory protection enabled, the agent is logging debug libc symbols unnecessarily. (EPP-5579)

Workaround

: Install the libc6-dbg package.

* Some files that are classified as threats are incorrectly shown as "waived" in the Cylance console when the file was added to the global safe list (instead of the local safe list) by an administrator. (EPP-5540)

* In some circumstances, if the device loses network connectivity and the agent is operating in offline mode, a malicious file is not quarantined even though the file was previously scored and determined to be a threat. (EPP-5093)

The agent updater proceeds to install the agent and driver (as if there's an update) even though the same version was already installed. The agent continues to run as expected and the unnecessary updates do not continue to occur. (EPP-2874)

After the installation of the agent, if the first agent update is not successful, the updater could not roll back the installation because the installation files cannot be found. (EPP-2726)

Workaround

: After installation, copy the each of the installation packages (.deb or .rpm) for the agent, drivers, and UI to the

/opt/cylance/desktop

directory.

2, installing the agent on newer kernels is successful, but a "CyProtectDrv: module verification failed: signature and/or required key missing - tainting kernel" error displays because a signature is missing. The agent still runs properly and the error can be ignored. (CHP-7335)
