Summary

Unsound usages of `core::slice::from_raw_parts_mut`

Details

The library breaks the safety assumptions when using unsafe API slice::from_raw_parts_mut. The pointer passed to from_raw_parts_mut is misaligned by casting u8 to u16 raw pointer directly, which is unsound. The bug is patched by using align_offset, which could make sure the memory address is aligned to 2 bytes for u16.

This was patched in 0.11.2 in the commit.
