The remote host is missing an update for the 'bpftool'
package(s) announced via the CESA-2020:5437 advisory.
Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es):
* kernel: metadata validator in XFS may cause an inode with a valid,
