{"id":"CVE-2026-111735","published":"2026-10-29T16:17:57.833","lastModified":"2026-10-29T16:26:37.430","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-125","CWE-191"],"vendors":[],"products":[],"references":[{"url":"https://rt-labs.com/wp-content/uploads/2026/10/RRTL-261019-01.pdf","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
