CVE-2026-31645
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z wyciekiem puli stron w ścieżkach błędów. Funkcja lan966x_fdma_rx_alloc() tworzy pulę stron, ale nie niszczy jej w przypadku niepowodzenia wywołania fdma_alloc_coherent(), co prowadzi do wycieku.
Risk Assessment
Wyciek pamięci może prowadzić do zwiększonego zużycia zasobów systemowych, co w dłuższej perspektywie może wpłynąć na stabilność i wydajność systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapobiec potencjalnym problemom z wydajnością.
