CVE-2025-39996
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z użyciem po zwolnieniu pamięci w funkcji flexcop_pci_remove. Problem wynikał z użycia cancel_delayed_work(), które nie gwarantowało, że opóźniona praca irq_check_work została w pełni zakończona.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianego zachowania systemu, co może skutkować awarią lub naruszeniem integralności danych. Organizacje powinny być świadome potencjalnych zagrożeń związanych z nieprawidłowym zarządzaniem pamięcią.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność. Regularne monitorowanie i aktualizowanie systemów jest kluczowe dla zapewnienia bezpieczeństwa.
