CVE-2025-39811
MediumSummary
W jądrze Linuxa rozwiązano podatność, która polegała na nieprawidłowym zarządzaniu wskaźnikiem błędu w funkcji xe_vm_free_scratch(). W przypadku wystąpienia błędu, wskaźnik scratch_pt nie był czyszczony, co mogło prowadzić do dereferencji wskaźnika błędu podczas sprzątania.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianych zachowań systemu, w tym potencjalnych awarii lub naruszeń bezpieczeństwa, co stanowi zagrożenie dla stabilności i integralności systemu operacyjnego.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe zarządzanie wskaźnikami błędów.
