CVE-2026-43372
MediumSummary
W jądrze Linuksa naprawiono podatność związaną z błędną obsługą ścieżki błędu podczas konfiguracji IRQ dla wiadomości PTP. W przypadku niepowodzenia funkcji request_threaded_irq() nowo utworzone mapowanie IRQ nie jest usuwane.
Risk Assessment
Brak odpowiedniego zwolnienia zasobów w przypadku błędu może prowadzić do wycieków pamięci lub innych problemów z wydajnością systemu, co może wpłynąć na stabilność aplikacji korzystających z PTP.
Recommendation
Zaleca się aktualizację jądra Linuksa do najnowszej wersji, aby usunąć tę podatność i poprawić zarządzanie zasobami w systemie.
