How to fix?

There is no fixed version for Centos:10 kernel-zfcpdump-modules-extra.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-extra package and not the kernel-zfcpdump-modules-extra package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

nfsd: move nfsd_debugfs_init() after nfsd4_init_slabs() in init_nfsd()

nfsd_debugfs_init() runs before nfsd4_init_slabs() in init_nfsd(). If the slab allocation fails, the bare "return retval" bypasses nfsd_debugfs_exit(), leaving orphan debugfs files with stale fops pointers into the freed module text.

Move nfsd_debugfs_init() to after the slab init succeeds, so the early return has no debugfs state to clean up.

Since debugfs is now the more recently initialized of the two, also update the unwind paths to match reverse-initialization (LIFO) order: run nfsd_debugfs_exit() before nfsd4_free_slabs() in both the init_nfsd() error path and exit_nfsd(). The nfsd debugfs files only reference module-global state and have no dependency on the slab caches, so that reordering is a cleanup with no functional change.
