CVE-2026-13481 Out-of-bounds read in PTP management TLV TIME parsing in Zephyr net PTP

The IEEE 1588 PTP management-message parser in subsys/net/lib/ptp/tlv.c mishandles the PTPMGMTTIME management id. In tlvmgmtpostrecv, the PTPMGMTTIME case casts mgmttlv-data to a 10-byte struct ptptimestamp and reads it then byte-swaps and writes it back without first checking that the TLV data...

CVE-2026-13480 Out-of-bounds read in LoRaWAN fragmented data block transport (FUOTA) downlink handler

The LoRaWAN TS004 Fragmented Data Block Transport handler fragtransportpackagecallback in subsys/lorawan/services/fragtransport.c parses downlink command bytes without validating that enough payload bytes remain before each access. The loop's only bound is rxpos fragsize, capped at...

CVE-2026-13217

The OCPP 1.6 client in subsys/net/lib/ocpp/ocpp.c reconstructs a session handle and PDU id from the uid field of a CALLRESULT message. In ocppprocessservermsg the code calls atoistrtokruid, "-", &tmp without checking the strtokr return value. When the server-supplied uid is empty or contains no -...

CVE-2026-13216

The virtio PCI driver drivers/virtio/virtiopci.c parses a device's PCI capability list during driver initialization. In virtiopcireadcap the device-supplied capability length byte caplen read from PCI config space via pcieconfread was only checked with asserttmp.caplen == capstructsize. That asse...

CVE-2026-13478 Out-of-bounds read in Zephyr ext2 block-bitmap validation from a crafted s_blocks_count

The Zephyr ext2 filesystem driver validates the on-disk block bitmap in ext2initfs subsys/fs/ext2/ext2impl.c by passing fsblocks = sblockscount - sfirstdatablock to ext2bitmapcountset. That helper subsys/fs/ext2/ext2bitmap.c treats its argument as a number of bits and reads one bitmap byte per...

CVE-2026-13215 Zephyr ext2 mount: unvalidated superblock block size causes out-of-bounds write from a crafted filesystem image

The Zephyr ext2 filesystem driver fails to validate the slogblocksize field of the on-disk superblock when mounting a filesystem. ext2verifydisksuperblock in subsys/fs/ext2/ext2impl.c checks the magic number, revision, inode size and group counts, but never bounds slogblocksize. On a successful...

CVE-2026-13214

A stack buffer overflow in the Zephyr RTOS OCPP 1.6 client (subsys/net/lib/ocpp/ocpp_j.c, function parse_getconfig_msg()) results from an unbounded strcpy() of an attacker-controlled JSON "key" string into a fixed 50-byte stack buffer (skey[CISTR50]). The key is parsed from a GetConfiguration mes...

EUVD-2026-65003

The Hearing Access Service HAS GATT server in subsys/bluetooth/audio/has.c installs a connection-callback set unconditionally via BTCONNCBDEFINE, so securitychanged runs for every connection that establishes security even before the application has called bthasregister. The service attribute...

CVE-2026-13343

CVE-2026-13343 affects the Zephyr RTOS UMP Stream responder library (lib/midi2/ump_stream_responder.c). The functions make_endpoint_info() and make_function_block_info() declare a local struct midi_ump without initialisation, populating only the first two of four uint32_t words. The remaining two...

CVE-2026-9728 TOCTOU race in mbox_send syscall verifier allows userspace to leak kernel memory

The userspace syscall verifier zvrfymboxsend in drivers/mbox/mboxhandlers.c validated the nested msg-data/msg-size fields by reading them directly out of live userspace memory, and then forwarded the original, still-mutable userspace struct mboxmsg pointer to zimplmboxsend and the underlying...

CVE-2026-9728

CVE-2026-9728 is a time-of-check/time-of-use (TOCTOU) race condition in the Zephyr RTOS userspace mailbox subsystem. The syscall verifier z_vrfy_mbox_send() in drivers/mbox/mbox_handlers.c validates msg->data/msg->size by reading them directly from live userspace memory, then forwards the o...

CVE-2026-9728 TOCTOU race in mbox_send syscall verifier allows userspace to leak kernel memory

The userspace syscall verifier zvrfymboxsend in drivers/mbox/mboxhandlers.c validated the nested msg-data/msg-size fields by reading them directly out of live userspace memory, and then forwarded the original, still-mutable userspace struct mboxmsg pointer to zimplmboxsend and the underlying...

CVE-2026-12634

The NVS backend of the Zephyr settings subsystem subsys/settings/src/settingsnvs.c reads stored setting-name entries into fixed 74-byte stack buffers and NUL-terminates them with bufrc = '\0', where rc is the return value of nvsread. Per its contract, nvsread returns the full stored entry length...

CVE-2026-12634 Out-of-bounds stack write in the settings NVS backend from over-reported nvs_read length

The NVS backend of the Zephyr settings subsystem subsys/settings/src/settingsnvs.c reads stored setting-name entries into fixed 74-byte stack buffers and NUL-terminates them with bufrc = '\0', where rc is the return value of nvsread. Per its contract, nvsread returns the full stored entry length...

CVE-2026-12633 Out-of-bounds write in IPv6 6LoWPAN Context Option handling via unauthenticated Router Advertisement

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...
