概要 このプロジェクトは、Shodanを使用した偵察とScapyを使用した悪意のあるIPv6パケットの作成・送信により、脆弱なWindowsシステムを特定し、CVE-2024-38063 を標的とした攻撃を実行するPythonスクリプトです。このツールは、脆弱なホストの検索、脆弱性の確認、そしてブルースクリーン（BSOD）を誘発するサービス拒否（DoS）攻撃の実行プロセスを自動化します。 CVE-2024-38063の解説 CVE-2024-38063...
CVE-2026-15893
netifipv6calcreachabletime in subsys/net/ip/netif.c derives a randomized ND reachable time from ipv6-basereachabletime as minreachable + sysrand32get % maxreachable - minreachable, where minreachable = base/2 and maxreachable = 3base/2 using integer division. When basereachabletime is 1, both...
CVE-2026-15893 Zephyr IPv6 Neighbor Discovery zero reachable time from crafted Router Advertisement causes assertion/DoS
netifipv6calcreachabletime in subsys/net/ip/netif.c derives a randomized ND reachable time from ipv6-basereachabletime as minreachable + sysrand32get % maxreachable - minreachable, where minreachable = base/2 and maxreachable = 3base/2 using integer division. When basereachabletime is 1, both...
CVE-2026-15893
CVE-2026-15893 affects the Zephyr RTOS IPv6 Neighbor Discovery stack. The function net_if_ipv6_calc_reachable_time() in subsys/net/ip/net_if.c computes a randomized reachable time from base_reachable_time using integer division. When the Reachable Time field of an incoming Router Advertisement is...

net if ipv6 calc reachable time in subsys/net/ip/net if.c derives a randomized ND reachable time from ipv6-base reachable time as min reachable + sys rand32 get % max reachable - min reachable, where min reachable = base/2 and max reachable = 3base/2 using integer division. When base reachable ti...
CVE-2026-12633
The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...

dhcpcd: dhcpcd infinite loop and out-of-bounds read via zero-length IPv6 ND option in Router Advertisement handling
A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser ...

The IPv6 Neighbor Discovery handlers in subsys/net/ip/ipv6nbr.c handlerainput, handlensinput, handlenainput used an incorrect boolean expression that combined the RFC 4861 validity checks with the ICMPv6 code check using the wrong operator precedence: the form was 'length/hop/source/target checks...
CVE-2026-7656 Broken IPv6 Neighbor Discovery input validation allows spoofed RA/NS/NA acceptance in Zephyr net stack
The IPv6 Neighbor Discovery handlers in subsys/net/ip/ipv6nbr.c handlerainput, handlensinput, handlenainput used an incorrect boolean expression that combined the RFC 4861 validity checks with the ICMPv6 code check using the wrong operator precedence: the form was 'length/hop/source/target checks...
CVE-2026-7656: Authentication Bypass by Spoofing

CVE-2026-10640 Use-after-free reading `net_pkt` `iface` after send in IPv6 Neighbor Discovery (`ipv6_nbr.c`)
Zephyr's IPv6 Neighbor Discovery send paths netipv6sendna, netipv6sendns, netipv6sendrs in subsys/net/ip/ipv6nbr.c updated the per-interface ICMP-sent statistics by calling netpktifacepkt after netsenddatapkt had already returned successfully. On the success path the network stack owns and releas...
CVE-2026-10640
Summary: Zephyr’s IPv6 Neighbor Discovery send paths (ipv6_nbr.c) perform a use-after-free by reading iface from a freed net_pkt slab block when updating per-interface ICMP statistics, after the packet has been sent. This can corrupt iface-stats.icmp.sent or cause a crash/DoS if the slab memory i...
