Oct 29, 2026P-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.CVE-2026-115795 · Other software · RT-Labs · reported by 4b71179a-3b92-4a9d-b9fc-af8b8ed579eeMedium 5.3
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.

Oct 29, 2026P-Net before 1.0.3 passes the application alarm callback a data length derived from the variable part length field of a received RTA alarm frame without checkinCVE-2026-115794 · Other software · RT-Labs · reported by 4b71179a-3b92-4a9d-b9fc-af8b8ed579eeLow 2.3
P-Net before 1.0.3 passes the application alarm callback a data length derived from the variable part length field of a received RTA alarm frame without checking it against the length of the received frame. A short frame can make the callback receive a length of up to 65507 bytes. An application that copies the reported number of bytes reads past the end of the receive buffer. The attacker must have established an Application Relationship and requires ADJACENT network access. Applications that do not use the alarm data are not affected.

Oct 29, 2026P-Net before 1.0.3 does not release the RPC session allocated for an RPC request that names an unknown interface or object UUID, and does not start a timeout foCVE-2026-115793 · Other software · RT-Labs · reported by 4b71179a-3b92-4a9d-b9fc-af8b8ed579eeHigh 8.7
P-Net before 1.0.3 does not release the RPC session allocated for an RPC request that names an unknown interface or object UUID, and does not start a timeout for it. Repeated requests with different activity UUIDs exhaust the available sessions. Once they are exhausted the device no longer answers new RPC requests, including Endpoint Mapper Lookup and Connect, until it is restarted. A remote unauthenticated attacker can use this to cause a denial of service.

P-Net before 1.0.3 does not release the Application Relationship (AR) and the RPC session when an RPC request is rejected because its data representation has incorrect endianness. The session and its AR remain allocated, so repeated requests exhaust the available sessions. Once they are exhausted the device no longer answers new RPC requests, including Connect, until it is restarted. A remote unauthenticated attacker can use this to cause a denial of service.

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).

P-Net before 1.0.3 contains an integer underflow in pf_cpm_c_data_ind(). When handling a received cyclic data frame while the consumer is in the FRUN or RUN state, the offset of the APDU status was computed as the frame length minus 4 using 16-bit arithmetic, without checking that the frame is long enough. A crafted short frame makes the offset wrap around, so the function reads outside the receive buffer. This can cause a crash (denial of service) or disclose memory content.

P-Net before 1.0.3 does not validate the length of a received Ethernet frame in pf_eth_recv() before reading the EtherType, any VLAN tags and the PROFINET FrameID. The VLAN tag loop had no upper bound, so a truncated frame, or a frame consisting only of VLAN tags, makes the function read past the end of the receive buffer. This can cause a crash (denial of service) or disclose memory content.

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).

P-Net before 1.0.3, when built with PNET_OPTION_AR_VENDOR_BLOCKS enabled, parses a data length from a field of the ARVendorBlock request that is not part of the block definition and uses it as the number of bytes to copy into a fixed-size buffer, without comparing it with the buffer size or the block length. A crafted Connect request causes an out-of-bounds write. This can lead to a crash (denial of service) or potentially arbitrary code execution. This option is disabled by default.

P-Net before 1.0.3 enters an infinite loop when handling a read request for the PDPortDataCheck record with subslot 0 (whole module). The loop over the ports never advanced to the next port, so the request never completes and the device stops responding. A remote unauthenticated attacker can use this to cause a denial of service.

P-Net before 1.0.3 does not validate the LengthPeerStationName field of a CheckPeers block in get_check_peer(). The received length (up to 255) was used to copy data into the 241-byte peer station name buffer and to place the terminating NUL byte, so a crafted block writes up to 15 bytes past the end of the buffer. This can lead to a crash (denial of service) or potentially arbitrary code execution. Requires establishment of session that needs ADJACENT network access.

In Apache CXF, the Netty-based HTTP client transport (cxf-rt-transports-http-netty-client) did not verify that the hostname in the server’s TLS certificate matched the host being called. This applied over both HTTP/1.1 and HTTP/2, even when disableCNCheck was left at its default value of false. The certificate chain was validated against the configured trust store, but the endpoint’s identity was not. A network attacker able to intercept traffic could present any certificate trusted by the client, such as a publicly issued certificate for a domain they control, and impersonate the target service. They could then read or modify the exchanged messages, including credentials. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
