Subject: [patch] sbshc: acpi_device_class "smbus_host_controller" too long
Date: Fri, 19 Mar 2010 11:44:11 +0000 [thread overview]
Message-ID: <20100319114411.GM5331@bicker> (raw)
acpi_device_class can only be 19 characters and a NULL terminator.
With the current name we get a buffer overflow in acpi_smbus_hc_add()
when we do:
strcpy(acpi_device_class(device), ACPI_SMB_HC_CLASS);
