CVE-2025-37829
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z funkcją scpi_cpufreq_get_rate(), która nie sprawdza, czy docelowy procesor jest obecny w masce policy->cpus. W przypadku braku procesora, cpufreq_cpu_get_raw() może zwrócić NULL, co prowadzi do dereferencji wskaźnika null.
Risk Assessment
Brak odpowiedniej walidacji może prowadzić do awarii systemu lub nieprzewidzianego zachowania, co stanowi zagrożenie dla stabilności i bezpieczeństwa systemu operacyjnego.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz zapewnić odpowiednie zabezpieczenia przed potencjalnymi atakami.

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.
