Live › vulnerability › CVE-2026-115795
P-Net, an industrial Profinet device stack, reads block headers past the end of the receive buffer in DCP Set and Identify requests. An attacker on the adjacent network can crash the device or read a small amount of its memory.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-29 16:25 UTC. All times on this page are UTC.
Devices or firmware that embed P-Net before 1.0.3 and accept Profinet DCP Set and Identify requests on their network. The attacker must be on the same adjacent network segment, so devices isolated from plant or building networks are less exposed. unknown whether specific vendor products are listed in the sources.

1.0.3.1.0.3Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
P-Net before 1.0.3 does not check that a complete block header is present in the received data before reading the next block in DCP Set and Identify requests. If the last block ends at the end of the receive buffer, the block length of the following block is read past the end of the buffer. In addition, a DCP Set block with a length smaller than the two-byte block qualifier makes the length underflow, so the block is processed with a length of 65534 bytes. This can cause a crash (denial of service) or disclose a small amount of memory content. Requires ADJACENT network access.
