Summary
P-Net, an open-source PROFINET device stack used in industrial networking equipment, is affected. A remote, unauthenticated attacker can send a specially crafted implicit read request that causes the device to crash, resulting in a denial of service.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
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).
