Full vulnerability record from the local CVENow database.
Description
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.

Se supone que blkcg_css_online fija el blkcg del padre, pero 397c9f46ee4d refactorizó las cosas y, de paso, lo modificó para fijar el CSS. Esto genera fijaciones adicionales y terminamos filtrando blkcgs y cgroups."
