Security Advisory
#################
Addressed in ACRN v2.3
************************
We recommend that all developers upgrade to this v2.3 release (or later), which
addresses the following security issue that was discovered in previous releases:
------
- NULL Pointer Dereference in ``devicemodel\hw\pci\virtio\virtio_mei.c``
``vmei_proc_tx()`` function tries to find the ``iov_base`` by calling
function ``paddr_guest2host()``, which may return NULL (the ``vd``
struct control by the User VM OS). There is a use of ``iov_base``
afterward that can cause a NULL pointer dereference (CVE-2020-28346).
**Affected Release:** v2.2 and earlier.
Addressed in ACRN v2.1
