CVE-2025-38113
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z ACPI i CPPC, która prowadziła do dereferencji wskaźnika NULL, gdy w linii poleceń użyto opcji nosmp. W przypadku, gdy inne procesory nie są uruchamiane, ich wskaźniki cpc_desc_ptr pozostają NULL, co może prowadzić do błędów.
Risk Assessment
Podatność ta może prowadzić do awarii systemu lub nieprzewidywalnego zachowania, co zagraża stabilności i bezpieczeństwu środowiska operacyjnego. Organizacje mogą doświadczyć przestojów lub utraty danych.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia potencjalnych problemów związanych z używaniem opcji nosmp.
