The LoRaWAN Fragmented Data Block Transport service subsys/lorawan/services/fragtransport.c does not validate the fragment counter in a received DATAFRAGMENT command before forwarding it to the configured decoder. In fragtransportpackagecallback the value fragcounter = hdr-fragindexn & 0x3FFF is...
CVE-2026-12364: Untrusted Pointer Dereference
The user-space system-call verifier zvrfyzlogmsgstaticcreate in subsys/logging/logmsg.c was a pure pass-through: it forwarded the caller-supplied source, desc, package, and data arguments directly to the kernel-mode implementation zimplzlogmsgstaticcreate without performing any of the mandatory...
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-2026-11368
The Bluetooth host ATT layer subsys/bluetooth/host/att.c associates each in-flight ATT TX buffer with its owning channel via the static txmetadatastorage array data-attchan = chan. When a buffer's last reference is dropped, its net-buf destroy callback defers the completion handling to the system...

CVE-2026-10849
The hawkBit device management client in subsys/mgmt/hawkbit accumulates the body of an HTTP response from the update server into a heap buffer in responsejsoncb subsys/mgmt/hawkbit/hawkbit.c. The buffer is sized to hold the received body bytes but reserves no space for a terminating NUL. When the...

The buffer is sized to hold the received body bytes but reserves no space for a terminating NUL. When the...
CVE-2026-10848
The OCPP 1.6 client in subsys/net/lib/ocpp parsed inbound WAMP RPC frames in parserpcmsg subsys/net/lib/ocpp/ocppj.c using a hand-rolled helper, extractstringfield, that copied the message's uid and action fields with strncpyoutbuf, token + 1, outlen - 1 and then scanned the result with...
CVE-2026-10686: Loop with Unreachable Exit Condition
Zephyr's IPv6 forwarding path re-sent routed unicast packets without ever decrementing the IPv6 hop limit. Both routing branches of ipv6routepacket subsys/net/ip were affected: the explicit-route path netroutepacket and the on-link cross-interface path netroutepacketif. Each set the packet...
CVE-2026-10682
The userspace verifier zvrfylogfilterset for the logfilterset syscall in subsys/logging/logmgmt.c performed a signed comparison against the int16t srcid parameter: srcid int16tlogsrccntgetdomainid. Any negative value for srcid e.g. -1 trivially satisfied this check and was forwarded into...
Zephyr buffer error vulnerability
Zephyr versions from 3.0.0 to 4.5.0 have a buffer error vulnerability. This vulnerability stems from the user-space verifier zvrfylogfilterset in the subsys/logging/logmgmt.c file. This verifier performs signed comparisons on the int16t srcid parameter. Negative values can bypass the verification...
