| Description: | vmm-sys-util is a collection of modules that provides helpers and
utilities used by multiple rust-vmm components. Starting in version
0.5.0 and prior to version 0.12.0, an issue in the
`FamStructWrapper::deserialize` implementation provided by the crate
for `vmm_sys_util::fam::FamStructWrapper` can lead to out of bounds
memory accesses. The deserialization does not check that the length
stored in the header matches the flexible array length. Mismatch in
the lengths might allow out of bounds memory access through Rust-safe
methods. The issue was corrected in version 0.12.0 by inserting a
check that verifies the lengths of compared flexible arrays are equal
for any deserialized header and aborting deserialization otherwise.
Moreover, the API was changed so that header length can only be
modified through Rust-unsafe code. This ensures that users cannot
trigger out-of-bounds memory access from Rust-safe code.
