Summary

In the Linux kernel, in the NFSD server, there is a crasher in nfsd4_encode_fattr4(). The issue is that args.acl is not initialized early, but it is used in an unconditional call to kfree() on the way out of the function, leading to a crash.

Risk Assessment

A crash of the NFS server can lead to unavailability of file services for clients, impacting business continuity. The fix prevents the crash.

Recommendation

Update the Linux kernel to a version with the fix that initializes args.acl early in nfsd4_encode_fattr4().
