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 5.5 (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.

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.
