CVE-2026-43195
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z walidacją rozmiarów kolejek użytkowników w sterowniku amdgpu. Wprowadzono sprawdzenie, aby rozmiary kolejek spełniały wymagania sprzętowe, takie jak bycie potęgą liczby dwa oraz minimalny rozmiar równy AMDGPU_GPU_PAGE_SIZE.
Risk Assessment
Brak odpowiedniej walidacji rozmiarów kolejek może prowadzić do nieefektywnego działania systemu oraz potencjalnych awarii. Organizacje mogą być narażone na problemy z wydajnością i stabilnością systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby skorzystać z wprowadzonych poprawek dotyczących walidacji rozmiarów kolejek w sterowniku amdgpu.
