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 ...

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-2026-10640 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...
