CVE-2026-12522 Stack buffer overflow in Zephyr hl7800 modem driver parsing network-supplied +CGCONTRDP address fields

The HL7800 cellular modem driver's +CGCONTRDP: response handler oncmdatcmdinfoipaddr in drivers/modem/vendorstandalone/hl7800.c parses the PDP-context dynamic parameters local address, subnet mask, gateway, and DNS servers that the cellular network assigns to the device. The response is linearize...

CVE-2026-12522

Zephyr RTOS's on_cmd_atcmdinfo_ipaddr() in drivers/modem/vendor_standalone/hl7800.c uses attacker-controlled delimiter positions as strncpy() length into fixed 64/16-byte buffers, causing stack overflow in supervisor context. A rogue base station can trigger crashes or control-flow hijacking. Fix...

CVE-2026-12520 Stack buffer overflow and off-by-one writes in Zephyr HL7800 modem AT response handlers

The Sierra Wireless HL7800 cellular modem driver drivers/modem/vendorstandalone/hl7800.c, located at drivers/modem/hl7800.c in v4.4.0 and earlier parses AT responses with roughly twenty handlers that call netbuflinearizevalue, sizeofvalue, buf, 0, len into a 128-byte stack buffer and then write...
