CVE-2026-57433
9.8 · CRITICALOverview
CVE-2026-57433 is a critical-severity vulnerability affecting nwclark storable. It was published on July 13, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from nwclark. Update storable to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
