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: nfsd: initialise nfsd_info.mutex early. nfsd_info.mutex can be dereferenced by svc_pool_stats_start() immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly be dereferenced.
