- Summary
- btrfs: zoned: initialize device's zone info for seeding
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: initialize device's zone info for seeding
When performing seeding on a zoned filesystem it is necessary to initialize each zoned device's btrfszoneddevice_info structure, otherwise mounting the filesystem will cause a NULL pointer dereference.
This was uncovered by fstests' testcase btrfs/163.
