CVE-2026-31780
MediumSummary
W jądrze Linuxa naprawiono podatność związaną z przepełnieniem zmiennej u8 w obliczeniach rozmiaru bufora skanowania SSID. Zmienna valuesize, zadeklarowana jako u8, akumuluje całkowitą długość wszystkich SSID do zeskanowania, gdzie każdy SSID może mieć do 33 bajtów.
Risk Assessment
Podatność ta może prowadzić do nieprzewidzianych zachowań systemu, co może wpłynąć na stabilność i bezpieczeństwo sieci bezprzewodowych w organizacji.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zminimalizować ryzyko związane z bezpieczeństwem sieci.
