Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: dlm: fix dlm_recover_members refcount on error If dlm_recover_members() fails we don't drop the references of the previous created root_list that holds and keep all rsbs alive during the recovery. It might be not an unlikely event because ping_members() could run into an -EINTR if another recovery progress was triggered again.
