CVE-2026-57433 on CTRL-OS 26.05

Aliases: CVE-2026-57433

Packages: perl

Status: Plausible

Advisory Information

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.
