CVE-2025-38104
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z dostępem do rejestrów RLCG, gdzie zamieniono mutex na spinlock, aby uniknąć inwersji priorytetów w SRIOV. Zmiana ta dotyczy bezpiecznego dostępu funkcji wirtualnych do rejestrów GPU w środowisku wirtualizowanym.
Risk Assessment
Brak zastosowania tej poprawki może prowadzić do problemów z wydajnością i stabilnością systemu w środowiskach wirtualnych, co może wpłynąć na działanie aplikacji korzystających z GPU.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby zastosować poprawkę eliminującą tę podatność oraz zminimalizować ryzyko związane z inwersją priorytetów.
