Recommended response

Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux.
Review the reported fix. Update Linux/Linux to a2fb51ec8920279e9e908010f37b448775f42eff if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source 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.
