CVE-2026-79981

The Zephyr RTOS DNS stub resolver (specifically in subsys/net/lib/dns/resolve.c) contains a vulnerability where it binds a single UDP socket per configured server during initialization. Because the source port remains constant for the lifetime of the resolver context while only the 16-bit transac...

CVE-2026-79981 DNS resolver reuses a single UDP source port for all queries, easing off-path answer spoofing

The DNS stub resolver in subsys/net/lib/dns/resolve.c binds one UDP socket per configured server when the resolver context is initialised dnsresolveinitlocked - registerdispatcher - dnsdispatcherregister, with the local port left at 0 so the stack picks an ephemeral port exactly once. dnswrite th...

CVE-2026-79977 WireGuard peer endpoint learned from unauthenticated transport-data messages allows off-path tunnel hijack in Zephyr

The WireGuard VPN service in subsys/net/lib/wireguard/wg.c updated the peer endpoint from a message it could not authenticate. In handletransportdata, when the 32-bit receiver index of an incoming transport-data message matched no session, the code both scheduled a new handshake and copied the...
