📋 Description

Impact

The get_disjoint_mut method in slab v0.4.10 incorrectly checked if indices were within the slab's capacity instead of its length, allowing access to uninitialized memory. This could lead to undefined behavior or potential crashes.

Patches

This has been fixed in slab v0.4.11.

Workarounds

Avoid using get_disjoint_mut with indices that might be beyond the slab's actual length, or upgrade to v0.4.11 or later.
