The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL.
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.
