CVE-2026-115863

ConnMan through 2.0 has a stack-based buffer overflow via a DHCPv6 Reply message. This occurs in getdomains in gdhcp/client.c. It copies a fixed NSMAXDNAME 1025 bytes from a DHCPv6 DOMAINLIST option 24 value into a 1026-byte stack buffer dnsname regardless of the actual option length, then walks...

CVE-2026-102551

Improper verification of the source of a communication channel in the IPv6 Router Advertisement handler in Amazon FreeRTOS-Plus-TCP before V4.4.2 might allow a remote third-party to influence an endpoint's IPv6 default gateway, on-link prefix, and address configuration via a crafted Router...

Astra Linux – Vulnerability in avahi

In Avahi, including versions 0.6.32 and 0.7, avahi-daemon inadvertently responds to IPv6 unicast queries with source addresses that are not on-link. This allows remote attackers to cause a denial of service traffic amplification and may lead to information leakage by extracting potentially...

CVE-2026-56116

A flaw was found in dhcpcd. An unauthenticated attacker on the same network link can exploit a memory leak vulnerability in the IPv6 Router Advertisement route information handling. By repeatedly sending specially crafted Router Advertisements with a zero lifetime, the attacker can cause the syst...

EUVD-2026-38496

dhcpcd through 10.3.2, fixed in commit 708b4a5, contains a memory leak vulnerability in the IPv6 Router Advertisement route information handling that allows an unauthenticated same-link attacker to cause denial of service by sending crafted Router Advertisements. Attackers can repeatedly send...

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...
