CVE-2024-56749

MEDIUM

Linux Kernel 6.10-6.10.9, 6.11.11-6.11.*, 6.12.0-6.12.1, 6.13 DoS via dlm_recover_members Ref Count Error

Title source: llm

Description

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.
