CVE-2025-39912 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: nfs/localio: restore creds before releasing pageio data Otherwise if the nfsd filecache code releases the nfsd_file immediately, it can trigger the BUG_ON(cred == current->cred) in __put_cred() when it puts the nfsd_file->nf_file->f-cred.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
