CVE-2025-38202
MediumSummary
W jądrze systemu Linux rozwiązano podatność związaną z funkcją bpf_map_lookup_percpu_elem(). Problem dotyczy sprawdzania, czy rcu_read_lock_trace_held() jest aktywne w kontekście tej funkcji, co może prowadzić do nieprawidłowego działania w przypadku wyłączonego BPF JIT lub na 32-bitowych hostach.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianych zachowań w programach BPF, co może wpłynąć na stabilność systemu oraz bezpieczeństwo danych przetwarzanych przez te programy.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność oraz zapewnić prawidłowe działanie funkcji BPF.

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.
