In the Linux kernel, the following vulnerability has been resolved: nfsd: fix possible badness in FREESTATEID When multiple FREESTATEIDs are sent for the same delegation stateid, it can lead to a possible either use-after-free or counter refcount underflow errors. In nfsd4freestateid() under the client lock we find a delegation stateid, however the code drops the lock before calling nfs4putstid(), that allows another FREE_STATE to find the stateid again. The first one will proceed to then free the stateid which leads to either use-after-free or decrementing already zeroed counter.
