CVE-2026-5072

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...

CVE-2026-5072

A bitwise shift vulnerability exists in Zephyr's PTP subsystem . A remote attacker can send a crafted PTP_MSG_MANAGEMENT message to set an unvalidated negative log_announce_interval value. When the system subsequently processes a PTP_MSG_ANNOUNCE message, the port_timer_set_timeout_random functio...
