## Overview

P-Net before 1.0.3 dereferences a NULL AR pointer in pf_fspm_cm_read_ind() when handling an implicit read request without a valid target AR UUID for a user specific record index, if the application has registered a read callback. A remote unauthenticated attacker can send such a request to crash the device (denial of service).

## Affected

- `P-Net < 1.0.3`

## Remediation

Upgrade to P-Net 1.0.3 or later.
