A flaw was found in the Linux kernel in versions before 5.12. The value of
internal.ndata, in the KVM API, is mapped to an array index, which can be
updated by a user process at anytime which could lead to an out-of-bounds
write. The highest threat from this vulnerability is to data integrity and
system availability.
