Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.
