CVE-2025-40273

In the Linux kernel, the following vulnerability has been resolved: NFSD: free copynotify stateid in nfs4freeolstateid Typically copynotify stateid is freed either when parent's stateid is being close/freed or in nfsd4laundromat if the stateid hasn't been used in a lease period. However, in case...

CVE-2025-40273

CVE-2025-40273 affects the Linux kernel NFSD code path nfs4_free_ol_stateid() where, after an OPEN creates a parent stateid and a subsequent COPY_NOTIFY is used, a reboot can expire the client and reveal a copynotify stateid still linked to the freed parent. The fix frees the associated copynotif...
