Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the /dev/vtpmx creation process within the tpm vtpm proxy driver. The /dev/vtpmx device becomes visible before the workqueue is initialized, potentially leading to memory corruption. The issue occurs during the driver initialization phase, specifically before the workqueue is properly set up. The workqueue is initialized as the first step of the driver initialization to address this.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
