Active exploitationNonot in the CISA catalog

Public exploitNot knownno public code found

ExtUtils::Typemaps::STL::Vector versions before 1.05 for Perl allocate a 32 GiB array on an empty list.

The OUTPUT typemaps call av_extend( av, len-1 ). On an empty list, this undeflows, and av_extend will allocate an array with 2^32 slots, leading to memory exhaustion.

CVSS

Base score: 7.5
Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.38 %
Percentile among all scored CVEs: 31
Score date: 10/21/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
