CVE-2026-43014
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z niewłaściwym wyrejestrowywaniem zegarów o stałej częstotliwości w module macb. Dodatkowe zasoby przydzielone przez clk_register_fixed_rate() muszą być zwolnione za pomocą clk_unregister_fixed_rate(), w przeciwnym razie zostaną utracone.
Risk Assessment
Niewłaściwe zarządzanie zasobami może prowadzić do wycieków pamięci, co w dłuższej perspektywie może wpłynąć na stabilność systemu. Organizacje mogą być narażone na problemy z wydajnością i dostępnością usług.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, w której ta podatność została naprawiona. Należy również monitorować systemy pod kątem potencjalnych problemów związanych z zarządzaniem zasobami.
