- Summary
- btrfs: zoned: clone zoned device info when cloning a device
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: clone zoned device info when cloning a device
When cloning a btrfsdevice, we're not cloning the associated btrfszoneddeviceinfo 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.
