This vulnerability allows a local attacker with low privileges to cause a denial of service (DoS) by triggering a NULL pointer dereference. This occurs when the iwl_pci_probe() function fails and frees a transaction structure, but the iwl_pci_remove() function subsequently attempts to access the already freed memory, leading to a system crash." ],
