CVE-2026-74603

CVE-2026-74603 is an over-read vulnerability in the Linux kernel's ptp: ocp module. The EEPROM board ID is a fixed 13-byte field not guaranteed to contain a NUL terminator; passing it directly to devlink_info_version_fixed_put() treats it as a C string, potentially reading beyond its intended mem...

CVE-2026-12632

In Zephyr RTOS, ptp_msg_post_recv() in subsys/net/lib/ptp/msg.c indexes the 14-entry msg_size[] table using an attacker-controlled 4-bit message type (0xE/0xF) with no bounds check, causing out-of-bounds reads and writes via msg_tlv_post_recv(). Any host on the same link can trigger a crash (CVSS...
