Out-of-bounds access in `get_disjoint_mut` due to incorrect…(CVE-2025-55159)

概要

Out-of-bounds access in get_disjoint_mut due to incorrect bounds check

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

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.
