What is CVE-2026-111733?

Versions of P-Net prior to 1.0.3 contain a flaw that allows a remote attacker to exploit a NULL AR pointer dereference. This occurs during the handling of an implicit read request when a valid target AR UUID for specific indices (0xE000-0xEFFF) is absent. By sending specially crafted requests, an attacker can crash the device, leading to a denial of service situation. It is crucial for users to apply the latest updates to safeguard against such potential threats.

Affected Version(s)
