## Summary

- **CVE ID:** CVE-2026-15811
- **Severity:** MEDIUM
- **CVSS Score:** 5.8 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L)

- **Published:** Jul 21, 2026
- **Last Modified:** Aug 21, 2026

## Description

A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability.
