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:
