Title
mailbox: zynq-ipi: fix error handling while device_register() fails
Summary
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:
1. The name allocated by dev_set_name() is leaked.
2. 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.
Severity ?
No CVSS data available.
