Description OSIDB Bzimport 2025-06-18 10:04:29 UTC 
In the Linux kernel, the following vulnerability has been resolved:

NFS/localio: Fix a race in nfs_local_open_fh()

Once the clp->cl_uuid.lock has been dropped, another CPU could come in
and free the struct nfsd_file that was just added. To prevent that from
happening, take the RCU read lock before dropping the spin lock.
