NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-extra package and not the kernel-uek-modules-extra package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

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.
