Last modified
CVE-2022-49786 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
