In the Linux kernel, the following vulnerability has been resolved: scsi: bfa: Double-free fix When the bfadimprobe() function fails during initialization, the memory pointed to by bfad->im is freed without setting bfad->im to NULL. Subsequently, during driver uninstallation, when the state machine enters the bfadsmstopping state and calls the bfadimprobe_undo() function, it attempts to free the memory pointed to by bfad->im again, thereby triggering a double-free vulnerability. Set bfad->im to NULL if probing fails.
