NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-4.19 package and not the linux-4.19 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

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.
