Description:
 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.
Ubuntu-Description:
 It was discovered that the btrfs file system in the Linux kernel did not
 properly validate metadata, leading to a NULL pointer dereference. An
 attacker could use this to specially craft a file system image that, when
 mounted, could cause a denial of service (system crash).
