Description OSIDB Bzimport 2025-09-18 14:04:49 UTC 
In the Linux kernel, the following vulnerability has been resolved:

NFS: Fix an Oops in nfs_d_automount()

When mounting from a NFSv4 referral, path->dentry can end up being a
negative dentry, so derive the struct nfs_server from the dentry
itself instead.
