CVE-2026-43274
MediumSummary
W jądrze Linuksa naprawiono podatność związaną z dostępem poza granice w funkcji mchp_ipc_get_cluster_aggr_irq(). Tablica cluster_cfg jest dynamicznie alokowana w celu przechowywania struktur konfiguracyjnych dla każdego CPU, a jej rozmiar zależy od liczby aktywnych CPU.
Risk Assessment
Niewłaściwy dostęp do pamięci może prowadzić do nieprzewidzianych zachowań systemu, w tym do awarii lub potencjalnego przejęcia kontroli nad systemem przez atakującego.
Recommendation
Zaleca się aktualizację jądra Linuksa do najnowszej wersji, aby usunąć tę podatność i zabezpieczyć system przed potencjalnymi atakami.
