      <title>CVE-2025-55159 — slab allows out-of-bounds access in `get_disjoint_mut` due to incorrect bounds check</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-55159</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; tokio-rs slab&lt;/p&gt;
&lt;p&gt;slab is a pre-allocated storage for a uniform data type. In version 0.4.10, the get_disjoint_mut method incorrectly checked if indices were within the slab&amp;#39;s capacity instead of its length, allowing access to uninitialized memory. This could lead to undefined behavior or potential crashes. This has been fixed in slab 0.4.11. A workaround for this issue involves to avoid using get_disjoint_mut with indices that might be beyond the slab&amp;#39;s actual length.&lt;/p&gt;</description>
