What is CVE-2026-111736?

P-Net prior to version 1.0.3 contains a security flaw that allows a remote unauthenticated attacker to make an implicit read request that dereferences a NULL AR pointer during the pf_fspm_cm_read_ind() operation. If a valid target AR UUID is not provided for a user-specific record index, and if a read callback is registered, this vulnerability can lead to the device crashing, resulting in a denial of service.

Affected Version(s)

P-Net 0 < 1.0.3
