CVE-2026-111734

7.1 high Published
NVD · CVE.org

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.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
