CVE-2023-54309

Estado: AplazadaSin puntuar—

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.
