CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability is an out-of-bounds write issue in the nfa_nfcee_act.cc file. It occurs because certain functions lack proper bounds checking, allowing memory beyond allocated limits to be written to. This can be exploited to gain elevated privileges on the device.

Impact Analysis

An attacker could exploit this to escalate privileges on your device without needing additional permissions or user interaction. This could allow them to gain control over sensitive functions or data on your device.

Compliance Impact

The vulnerability involves a possible out-of-bounds write due to missing bounds checks, enabling local privilege escalation. This could potentially allow unauthorized access to sensitive data or system functions, which may impact compliance with standards like GDPR or HIPAA by increasing risks of data breaches or unauthorized processing.

Mitigation Strategies

Apply the latest security patches from Google for Android to address the missing bounds check in nfa_nfcee_act.cc. Monitor official Android security bulletins for updates.
