CVE-2026-16515

CVE-2026-16515 affects the Zephyr RTOS IPv6 stack in net_icmpv6_send_error() (subsys/net/ip/icmpv6.c), which failed to implement two of the three RFC 4443 §2.4 suppression rules for ICMPv6 error replies. An unauthenticated attacker on the same link can trigger ICMPv6 reflection and amplification ...

CVE-2026-16512 Out-of-bounds read in the Zephyr gPTP receive path when handling short Ethernet frames

gptphandlemsg in subsys/net/l2/ethernet/gptp/gptp.c dereferenced the gPTP header returned by GPTPHDR and switched on hdr-messagetype without first checking that the received frame carries at least sizeofstruct gptphdr 34 bytes of payload. The header accessor gptpgethdr deliberately never fails fo...

CVE-2026-16512

CVE-2026-16512 is an out-of-bounds read in the Zephyr RTOS gPTP (generalized Precision Time Protocol) receive path. In gptp_handle_msg() (subsys/net/l2/ethernet/gptp/gptp.c), the gPTP header is dereferenced without verifying the frame carries at least 34 bytes of payload. The GPTP_VALID_LEN() che...
