CVE-2026-115794 Details
Description
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.
A buffer overflow vulnerability has been identified in P-Net versions prior to 1.0.3. The issue arises when the application alarm callback is passed a data length derived from the variable part length field of a received RTA alarm frame, without validating it against the actual length of the received frame. This oversight allows a short frame to manipulate the callback into receiving a length of up to 65507 bytes. Consequently, an application that copies the reported number of bytes may read past the end of the receive buffer. The vulnerability requires an established Application Relationship and adjacent network access. Applications that do not utilize the alarm data are not impacted.
Users are advised to upgrade to P-Net version 1.0.3 or later, where this vulnerability has been fixed.
