CVE-2024-56749
Estado: ModificadaMedia (5.5)—
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.
