CVE-2026-31523
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z obsługą kolejek polled w sterowniku nvme-pci. Użytkownik może zmieniać liczbę kolejek polled w czasie rzeczywistym, co może prowadzić do problemów podczas resetu, gdy zadanie o wysokim priorytecie próbuje odpytywać tę kolejkę przed jej aktualizacją przez warstwę blokową.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianych zachowań systemu, co może wpłynąć na stabilność i wydajność operacji dyskowych. W przypadku wykorzystania tej luki, atakujący może zyskać możliwość zakłócenia działania systemu.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, w której ta podatność została załatana. Należy również monitorować systemy pod kątem nieautoryzowanych zmian w konfiguracji kolejek polled.
