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 Precision Time Protocol receive handler ptp msg post recv in subsys/net/lib/ptp/msg.c takes the 4-bit message type straight off the wire via ptp msg type msg-header.type major sdo id & 0xF, range 0-15 and uses it to index the msg size table. That table only defines entries up to PTP MSG...

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...
