CVE-2026-11812

The UpdateHub management subsystem subsys/mgmt/updatehub/updatehub.c drives every update operation through a single file-scope ctx structure that holds the CoAP block context, payload buffer, status code, socket, and a one-element poll-fd array fds1. Access to ctx was not serialized, and preparef...

CVE-2026-11811

The UpdateHub over-the-air update client's startcoapclient in subsys/mgmt/updatehub/updatehub.c leaks the CoAP/DTLS socket descriptor on its connection-setup failure paths. The shared error: cleanup gated socket closing on a ret 0 flag, but ret was set to -1 immediately after the socket was...
