CVE-2025-38258
MediumSummary
W jądrze Linuxa zidentyfikowano podatność polegającą na niezwalnianiu wcześniej przydzielonej pamięci w funkcji memcg_path_store(). Nowo przydzielony bufor pamięci jest przypisywany do filter->memcg_path, co prowadzi do wycieku pamięci.
Risk Assessment
Wyciek pamięci może prowadzić do zwiększonego zużycia zasobów systemowych, co w dłuższej perspektywie może wpłynąć na stabilność i wydajność systemu.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, w której ta podatność została naprawiona, aby zminimalizować ryzyko wycieków pamięci.

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.
