Description

Bitmap::try_from(&[u8]) can create invalid values

The TryFrom<&[u8]> implementation for Bitmap<SIZE> copies the input bytes

into an uninitialized backing store and calls assume_init() without

validating that the bytes form a valid value of the backing store type. For

SIZE = 1 the backing store is a bool, so any input byte other than 0x00

or 0x01 produces an invalid value, which is immediate undefined behavior.

The AsMut<[u8]> implementation has the same problem, as it allows safe code

to write invalid bit patterns into the backing store through the returned slice.

No fixed version is available, as the crate is unmaintained; its GitHub

repository was archived by the owner on 2026-05-03.
