FKIE_CVE-2026-57433

Vulnerability from fkie_nvd - Published: 2026-07-13 17:17 - Updated: 2026-07-13 20:16
Severity
Summary
Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record. 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. 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.
