Weakness Types
What is a Stack Exhaustion Vulnerability?
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
CVE-2025-8696 has been classified to as a Stack Exhaustion vulnerability or weakness.
Logging of Excessive Data
The software logs too much information, making log files hard to process and possibly hindering recovery efforts or forensic analysis after an attack. While logging is a good practice in general, and very high levels of logging are appropriate for debugging stages of development, too much logging in a production environment might hinder a system administrator's ability to detect anomalous conditions. This can provide cover for an attacker while attempting to penetrate a system, clutter the audit trail for forensic analysis, or make it more difficult to debug problems in a production environment.
