What it is

In the Linux kernel, the following vulnerability has been resolved:

btrfs: zoned: clone zoned device info when cloning a device

When cloning a btrfs_device, we're not cloning the associated

btrfs_zoned_device_info structure of the device in case of a zoned

filesystem.

Later on this leads to a NULL pointer dereference when accessing the

device's zone_info for instance when setting a zone as active.

This was uncovered by fstests' testcase btrfs/161.
