Description:
The vulnerability is related to the Linux kernel, specifically in the drivers/virt/acrn component. It involves issues with PFNMAP PTE checks in the acrn vm ram map() function. The problem arises from missing handling of various cases, resulting in dangerous usage of the follow pte() function.
