CVE-2023-33119: Memory corruption while loading a VM from a signed VM image that is not coherent in the processor cache.

CVE-2023-33119 is a memory corruption vulnerability that occurs when loading a virtual machine (VM, a simulated computer running inside another computer) from a signed VM image that is not coherent in the processor cache (the fast memory where a processor stores copies of data). The vulnerability is related to a TOCTOU race condition (a timing flaw where data can change between when it is checked and when it is used).
