Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition in the nfs local open fh() function has been resolved. The issue occurs when the clp->cl uuid.lock is dropped, allowing another CPU to potentially free the struct nfsd file that was just added. To prevent this, the RCU read lock is taken before dropping the spin lock.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
