CVE-2026-107838

RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. From version 2023.07 through version 2026.07, nanocoapfileserver callers in sys/net/applicationlayer/nanocoap/fileserver.c ignore a failure returned by respinit when...

CVE-2026-107838 RIOT: nanocoap_fileserver ignores response initialization failure, leading to reachable assertion

RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. From version 2023.07 through version 2026.07, nanocoapfileserver callers in sys/net/applicationlayer/nanocoap/fileserver.c ignore a failure returned by respinit when...

CVE-2026-107838

The RIOT microcontroller operating system (versions 2023.07 through 2026.07 ) is vulnerable to a reachable assertion in the nanocoap_fileserver component. The root cause is that callers in sys/net/application_layer/nanocoap/fileserver.c ignore a failure returned by _resp_init() when coap_build_re...
