This script is designed to patch kernel modules for VMware Workstation 17.0.1 and sign the resulting code.

To use this script, simply execute it in a terminal with administrative privileges:

sudo ./vmware-kernel-fix.sh

The script has three main functions:

• install_tools: Installs the necessary tools required by the script such as openssl

• patch_vmware_modules: Clones the vmware-host-modules repository into a temporary folder, checks out the specified version, compiles and installs the modules, and then fixes an issue with the libz.so.1 library.

• sign_vmware_modules: This function creates a directory for the keys and a key pair, imports the key into the system's database, and signs each of the VMware module files.

The script uses the following variables:

• VMWARE_VERSION: Defines the version of VMware Workstation or Player to be patched

• TMP_FOLDER: Defines the temporary folder used to clone the vmware-host-modules repository. It defaults to /tmp/patch-vmware
