Official description
In the Linux kernel, the following vulnerability has been resolved:
power: sequencing: fix NULL-pointer dereference in pwrseq_device_register()
If dev_set_name() fails in pwrseq_device_register(), we jump to the err_put_pwrseq label before initializing pwrseq->targets. pwrseq_release() will try to iterate over targets unconditionally and subsequently dereference an invalid pointer. Move the call to dev_set_name() after the list head is initialized.
