Impact

Out-of-bounds reads can leak sensitive information from memory, while out-of-bounds writes can corrupt data or enable code execution. With a CVSS score of 6.1 (MEDIUM), this represents a moderate risk.
Exploit ScenarioDerived

An attacker provides a crafted input that causes the application to read or write beyond buffer boundaries, potentially leaking memory contents or hijacking control flow.
This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

DescriptionCVE.org

A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the setpwnam() function, affecting SUID (Set User ID) login-utils utilities writing to the password database.

Executive ViewAI

Why It Matters

Organizations using A flaw should be aware of moderate risk from CVE-2025-14104, a out-of-bounds read vulnerability rated CVSS 6.1. Exploitation could cause memory corruption or application crashes. Organizations should apply vendor updates when available and monitor for exploitation.

Business Impact: Low
Compensating Controls

Apply vendor patch. If patching is delayed: enable ASLR/DEP, apply network segmentation.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
