CVE-2026-31548
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z modułem wifi, która dotyczy anulowania zadania pmsr_free_wk w funkcji cfg80211_pmsr_wdev_down. Problem występuje, gdy gniazdo nl80211, które zainicjowało żądanie PMSR, jest zamykane.
Risk Assessment
Podatność ta może prowadzić do nieprawidłowego przetwarzania żądań PMSR, co może wpłynąć na stabilność i bezpieczeństwo połączeń sieciowych w systemie.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemu pod kątem nieautoryzowanych żądań PMSR.
