CVE-2025-40353
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z funkcją copy_highpage() dla architektury arm64, która zakłada, że docelowa strona jest nowo przydzielona i nie jest oznaczona tagiem MTE. W przypadku, gdy strona jest już oznaczona, funkcja nie powinna generować ostrzeżenia.
Risk Assessment
Podatność ta może prowadzić do nieprawidłowego działania systemu, jeśli strona docelowa jest już oznaczona, co może wpływać na integralność danych i stabilność systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe działanie funkcji copy_highpage().
