CVE-2023-21264
This could lead to local escalation of privilege with System execution privileges needed.
Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
Description
In multiple functions of mem_protect.c, there is a possible way to access hypervisor memory due to a memory access check in the wrong place. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
