CVE-2026-13481 Out-of-bounds read in PTP management TLV TIME parsing in Zephyr net PTP

The IEEE 1588 PTP management-message parser in subsys/net/lib/ptp/tlv.c mishandles the PTPMGMTTIME management id. In tlvmgmtpostrecv, the PTPMGMTTIME case casts mgmttlv-data to a 10-byte struct ptptimestamp and reads it then byte-swaps and writes it back without first checking that the TLV data...

CVE-2026-13481

CVE-2026-13481 is an out-of-bounds read in the IEEE 1588 PTP management-message parser in Zephyr RTOS (subsys/net/lib/ptp/tlv.c). In tlv_mgmt_post_recv(), the PTP_MGMT_TIME case casts TLV data to a 10-byte ptp_timestamp struct without validating that the data field is at least that size, unlike a...

CVE-2026-5072 ptp: Potential Denial of Service via PTP Interval Shift

A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTPMSGMANAGEMENT message to set an unvalidated negative logannounceinterval value in the port's data set. When a subsequent...
