CVE-2018-14722
Code execution as root can occur via a specially crafted filesystem label if btrfs-{scrub,balance,trim} are set to auto in /etc/sysconfig/btrfsmaintenance (this is not the default, though).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
