CVE-2026-111733 Details
Description
P-Net before 1.0.3 dereferences a NULL AR pointer when handling an implicit read request without a valid target AR UUID for a record index that requires an AR (AR specific indices 0xE000-0xEFFF, and the expected identification data of a slot or subslot). A remote unauthenticated attacker can send such a request to crash the device (denial of service).
A NULL pointer dereference vulnerability has been identified in P-Net versions prior to 1.0.3. The issue arises when the software processes an implicit read request for AR-specific record indices (0xE000-0xEFFF) without a valid target AR UUID. This oversight leads to a crash, causing a denial-of-service condition on the device. The vulnerability can be exploited by remote, unauthenticated attackers.
Users are advised to upgrade to P-Net version 1.0.3 or later, where this vulnerability has been fixed.
