Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: return EIO on RAID1 block group write pointer mismatch
There was a bug report about a NULL pointer dereference in
__btrfs_add_free_space_zoned() that ultimately happens because a
conversion from the default metadata profile DUP to a RAID1 profile on two
disks.
The stack trace has the following signature:
BTRFS error (device sdc): zoned: write pointer offset mismatch of zones in raid1 profile
BUG: kernel NULL pointer dereference, address: 0000000000000058

The 1st line is the most interesting here:
BTRFS error (device sdc): zoned: write pointer offset mismatch of zones in raid1 profile
When a RAID1 block-group is created and a write pointer mismatch between
the disks in the RAID set is detected, btrfs sets the alloc_offset to the
length of the block group marking it as full. Afterwards the code expects
that a balance operation will evacuate the data in this block-group and
repair the problems.
But before this is possible, the new space of this block-group will be
accounted in the free space cache. But in __btrfs_
