Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: properly pin the parent in blkcg_css_online
blkcg_css_online is supposed to pin the blkcg of the parent, but
397c9f46ee4d refactored things and along the way, changed it to pin the
css instead. This results in extra pins, and we end up leaking blkcgs
and cgroups.
