In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_vtpm_proxy: fix a race condition in /dev/vtpmx creation
/dev/vtpmx is made visible before 'workqueue' is initialized, which can lead to a memory corruption in the worst case scenario.
Address this by initializing 'workqueue' as the very first step of the driver initialization.
