Answer in brief
CVE-2026-111735 records a High severity (CVSS 7.1) vulnerability in Integer underflow leads to out-of-bounds read in pf_cpm_c_data_ind(). The current sources do not mark it as known exploited. The current feed maps RT-Labs/P-Net (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
