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...

CVE-2026-12519 Out-of-bounds stack read and write in Zephyr WNC-M14A2A modem socket-notify parsing

The WNC-M14A2A LTE-M modem driver mishandles unsolicited %NOTIFYEV: events in oncmdsocknotifyev drivers/modem/vendorstandalone/wncm14a2a.c. The response line is linearized into a fixed 40-byte stack buffer via netbuflinearize, which caps the copy at 39 bytes and returns outlen = 39. The two...

CVE-2026-20479

In Modem, there is a possible out of bounds read due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation...
