CVE-2026-31510
MediumSummary
W jądrze systemu Linux naprawiono podatność związaną z Bluetooth, która mogła prowadzić do dereferencji wskaźnika null w funkcji l2cap_sock_ready_cb. Przed użyciem wskaźnika sk, dodano sprawdzenie, czy jest on równy null.
Risk Assessment
Podatność ta mogła prowadzić do awarii systemu lub nieprzewidzianego zachowania aplikacji korzystających z Bluetooth, co stwarza ryzyko dla stabilności i bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność i zapewnić bezpieczeństwo operacji związanych z Bluetooth.

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.

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.
