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

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...

SUSE CVE-2026-44318

free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's BSF PUT /nbsf-management/v1/subscriptions/subId handler has an unsynchronized write on the global Subscriptions map. The handler first reads the map under RLock via BSFContext.GetSubscriptionsubId, but if t...

Ella Core is a 5G core designed for private networks. Prior to 1.10.0, Ella Core does not verify the UE Security Capabilities received in NGAP PathSwitchRequest messages against its locally stored values. A malicious gNB can overwrite Ella Core's stored UE security capabilities for any UE with...

GNSS Spoofing Detection in TDD Networks: A 3GPP Standards-Based Security Framework

Time Division Duplex TDD mobile networks require synchronization accuracy of $\pm$1.5 $μ$s 3GPP TS 38.104, with GNSS-disciplined grandmaster clocks as the predominant timing source. GNSS spoofing -- now a documented operational threat -- can corrupt timing across all downstream base stations, yet...
