      <title>CVE-2026-57433 — Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-57433</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; HAARG Storable&lt;/p&gt;
&lt;p&gt;Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.&lt;/p&gt;
&lt;p&gt;retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value.&lt;/p&gt;
&lt;p&gt;A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.&lt;/p&gt;</description>
