CVE-2025-38274
MediumSummary
W jądrze Linuxa zidentyfikowano podatność, która została naprawiona. Funkcja fpga_mgr_test_img_load_sgt() alokuje pamięć dla sgt przy użyciu kunit_kzalloc(), ale nie sprawdza, czy alokacja się powiodła, co może prowadzić do dereferencji wskaźnika null.
Risk Assessment
Brak sprawdzenia poprawności alokacji pamięci może prowadzić do awarii systemu lub nieprzewidzianego zachowania aplikacji, co stwarza ryzyko dla stabilności i bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz wprowadzenie dodatkowych kontroli błędów w kodzie, aby zapobiec podobnym problemom w przyszłości.

Etrel INCH AC charging station management web interface prior to firmware versions 7.1.2 and 8.0.1 contains a hard-coded default credentials vulnerability that allows remote attackers to gain full Administrator access by authenticating with the factory-default account. Attackers can log in over cleartext HTTP to obtain complete charger configuration, OCPP ChargePoint Identity, and CSMS WebSocket connection details, enabling unauthorized administrative control of the charging station.
- CVE-2026-95860Critical
In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.
