Ubuntu.comUB:CVE-2021-47258CVE-2021-47258
In the Linux kernel, the following vulnerability has been resolved: scsi:
core: Fix error handling of scsi_host_alloc() After device is initialized
via device_initialize(), or its name is set via dev_set_name(), the device
has to be freed via put_device(). Otherwise device name will be leaked
because it is allocated dynamically in dev_set_name(). Fix the leak by
replacing kfree() with put_device(). Since scsi_host_dev_release() properly
handles IDA and kthread removal, remove special-casing these from the error
handling as well.
