Details

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.

Severity

5.5 (Medium)
