CVE-2026-43022
MediumSummary
W jądrze Linuxa rozwiązano podatność związaną z funkcją hci_cmd_sync_queue_once(), która nieprawidłowo informowała, czy element kolejki został dodany. To mogło prowadzić do wycieków zasobów, jeśli nie byłyby wywoływane odpowiednie funkcje zwrotne.
Risk Assessment
Organizacje mogą być narażone na problemy z zarządzaniem zasobami, co może prowadzić do obniżenia wydajności systemu lub jego destabilizacji.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe zarządzanie kolejkami Bluetooth.
