  "description": "In a typical Virtual Machine Monitor (VMM) there are several components, such as boot loader, virtual device drivers, virtio backend drivers and vhost drivers, that need to access the VM physical memory. The vm-memory rust crate provides a set of traits to decouple VM memory consumers from VM memory providers. An issue was discovered in the default implementations of the \u0060VolatileMemory::{get_atomic_ref, aligned_as_ref, aligned_as_mut, get_ref, get_array_ref}\u0060 trait functions, which allows out-of-bounds memory access if the \u0060VolatileMemory::get_slice\u0060 function returns a \u0060VolatileSlice\u0060 whose length is less than the function\u2019s \u0060count\u0060 argument. No implementations of \u0060get_slice\u0060 provided in \u0060vm_memory\u0060 are affected. Users of custom \u0060VolatileMemory\u0060 implementations may be impacted if the custom implementation does not adhere to \u0060get_slice\u0060\u0027s documentation. The issue started in version 0.1.0 but was fixed in version 0.12.2 by inserting a check that verifies that the \u0060VolatileSlice\u0060 returned by \u0060get_slice\u0060 is of the correct length. Users are advised to upgrade. There are no known workarounds for this issue.",
