CVE-2026-98091CVE-2026-98091
Description
In the Linux kernel, the following vulnerability has been resolved:
btrfs: detach failed sprout device from transaction update list
When creating the first metadata chunk for a sprout filesystem,
create_chunk() adds the new device to the transaction dev_update_list
through device->post_commit_list.
If the subsequent system chunk creation fails, btrfs_init_new_device()
aborts the transaction and releases the device while post_commit_list is
still linked. This triggers a warning in btrfs_free_device() and leaves
the transaction list referencing freed memory.
Detach the device while holding chunk_mutex before releasing it.
