Technical Description
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
#PF: supervisor read access in kernel mode
