CVE-2026-11810

The UpdateHub firmware-update agent's probe handler zimplupdatehubprobe in subsys/mgmt/updatehub/updatehub.c parses the JSON metadata returned by the update server into a fixed two-level nested-array struct. After parsing it validates only the outer array length objectslen != 2 and then...

CVE-2026-11809

CVE-2026-11809 (Zephyr UpdateHub OTA client) : The UpdateHub probe in subsys/mgmt/updatehub/updatehub.c uses a second heap buffer (metadata_copy) via memcpy(metadata_copy, metadata, strlen(metadata)) without zeroing. This omits the terminating NUL, so a subsequent json_obj_parse(metadata_copy, st...
