- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mailbox: zynq-ipi: fix error handling while device_register() fails
If device_register() fails, it has two issues:
- The name allocated by dev_set_name() is leaked.
- The parent of device is not NULL, device_unregister() is called in zynqmp_ipi_free_mboxes(), it will lead a kernel crash because of removing not added device.
Call put_device() to give up the reference, so the name is freed in kobject_cleanup(). Add device registered check in zynqmp_ipi_free_mboxes() to avoid null-ptr-deref.
