Name of the Vulnerable Software and Affected Versions Zephyr OS affected versions not specified Description An out-of-bounds write can occur in the ieee802154 send function within subsys/net/l2/ieee802154/ieee802154.c. When CONFIG NET L2 IEEE802154 FRAGMENT is enabled and 6LoWPAN fragmentation is...
CVE-2026-14366
The Silicon Labs SiWx917 WiFi driver's transmit callback siwx91xsend in drivers/wifi/siwx91x/siwx91xwifi.c frees a network packet it does not own. In the Zephyr TX path the netpkt is owned by the L2/networking stack; the driver only borrows it to copy the frame bytes into a local netbuf. Before t...
CVE-2026-12634
In Zephyr's settings NVS backend (subsys/settings/src/settings_nvs.c), three functions (settings_nvs_cache_match, settings_nvs_load, settings_nvs_save) use the nvs_read() return value directly as a NUL-terminator index into 74-byte stack buffers without clamping, causing a single-byte out-of-boun...

Zephyr's 6LoWPAN IP Header Compression IPHC uncompression code contains an out-of-bounds read in get ihpc inlined size subsys/net/ip/6lo.c. The destination inline size is looked up in da inline size table, which has 13 entries, using an index built from the M, DAC and DAM bits of the received IPH...
CVE-2026-12364
The CVE-2026-12364 issue affects the Zephyr kernel’s user-space syscall verifier z_vrfy_z_log_msg_static_create(). The verifier failed to enforce K_SYSCALL_* checks when forwarding source, desc, package, and data to z_impl_z_log_msg_static_create(), allowing an attacker-controlled user-space thre...
CVE-2026-12232
The Intel ALH digital-audio-interface driver function daialhgetproperties in drivers/dai/intel/alh/alh.c used a caller-supplied int streamid with no range validation. The value indexes the fixed-size static const uint8t alhhandshakemap64 array and scales a FIFO register address, so an out-of-rang...
CVE-2026-12052
The CVE-2026-12052 issue affects Zephyr’s USB device CDC NCM class (usbd_cdc_ncm_cth in subsys/usb/device_next/class/usbd_cdc_ncm.c). The handler builds fixed-size responses for GET_NTB_PARAMETERS (28-byte) and GET_NTB_INPUT_SIZE (8-byte) and copies the entire structure into the control DATA IN b...
CVE-2026-12052 Out-of-bounds write in USB CDC NCM control handler when host wLength is smaller than the response
The USB device-side CDC NCM class control-to-host handler usbdcdcncmcth in subsys/usb/devicenext/class/usbdcdcncm.c builds a fixed-size response for the GETNTBPARAMETERS 28-byte struct ntbparameters and GETNTBINPUTSIZE 8-byte struct ntbinputsize class requests and copies the whole structure into...

Name of the Vulnerable Software and Affected Versions Bouffalo Lab on-chip BLE controllers BL60x/BL70x/BL61x affected versions not specified Description The Bluetooth HCI driver for Bouffalo Lab on-chip BLE controllers contains an issue where the bt bflb send function in drivers/bluetooth/hci/hci...
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...
EUVD-2026-55854
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...
EUVD-2026-55843
The UpdateHub OTA client in subsys/mgmt/updatehub/updatehub.c contains an out-of-bounds / uninitialized-memory read in zimplupdatehubprobe. The probe response from the UpdateHub server is copied into a heap buffer metadata that is correctly NUL-terminated, but a second buffer metadatacopy is...
CVE-2026-11810
CVE-2026-11810 affects Zephyr’s UpdateHub firmware-update agent. The probe handler z_impl_updatehub_probe() parses CoAP-provided JSON metadata into a two-level nested array; it only validates the outer array length and then dereferences objects[1].objects[0].objects.sha256sum with strlen() withou...
