Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Attack-Flow Graph

Executive Summary

This vulnerability is an integer overflow that can lead to an out of bounds write in multiple locations. It allows local privilege escalation without needing additional execution privileges or user interaction.

Impact Analysis

An attacker could exploit this to gain elevated privileges on your system, potentially allowing them to take control of your device or access sensitive data.

Mitigation Strategies

Apply the latest security patches from the vendor immediately. Since this is a local privilege escalation vulnerability, ensure all systems are updated to the latest version to prevent exploitation. Monitor for unusual activity or unauthorized privilege changes.
