CVE-2019-18885
fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15.

Does this matter?
Lower severity and a low EPSS score (1.22%). Track it; it rarely justifies an emergency change on its own.
