Summary
W jądrze Linux wykryto podatność use-after-free w module nft_tunnel. Funkcja nft_tunnel_obj_destroy() wywołuje metadata_dst_free(), które bezpośrednio zwalnia pamięć metadata_dst, ignorując licznik odwołań dst_entry. Pakiety, które przechowują referencję przez dst_hold() w nft_tunnel_obj_eval() i są nadal w kolejce (np. w netem qdisc), pozostają z wiszącym wskaźnikiem, co prowadzi do użycia po zwolnieniu przy ich dalszym przetwarzaniu.
Risk Assessment
Podatność może prowadzić do awarii systemu (kernel panic) lub potencjalnie do wykonania dowolnego kodu w kontekście jądra, co stanowi poważne ryzyko dla stabilności i bezpieczeństwa systemu.
