Low risk3th percentile - higher than 3% of all known CVEs
Summary
W jądrze Linuxa w module IPVS wykryto podatność polegającą na tym, że podczas edycji usługi (ip_vs_edit_service) wskaźnik do starego schedulera (svc->scheduler) był czyszczony dopiero po zainicjowaniu przez moduł schedulera wywołań zwrotnych RCU. Może to prowadzić do użycia starego schedulera po zwolnieniu jego danych (sched_data) po upływie okresu RCU, co skutkuje błędami lub awariami.
Risk Assessment
Organizacja narażona jest na potencjalne błędy w działaniu IPVS, w tym użycie nieprawidłowych danych schedulera, co może prowadzić do nieoczekiwanego zachowania równoważenia obciążenia, a w skrajnych przypadkach do awarii systemu.
