Summary

The Linux kernel btrfs filesystem code from 3.7 is affected. When updating an inode fails during hole punching or reflinking, the error path returns without aborting the transaction, after file extent items were already dropped. If the transaction is later committed, this can leave a persistent filesystem inconsistency.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: btrfs: abort transaction on failure to update inode for hole punching and reflinking If we fail to update the inode we error out without aborting the transaction, which can result in a persistent inconsistency if after the failure the transaction is committed, as we have dropped file extent items from a range and either punched a hole or insert a new file extent item for that range (for reflinks). So add the missing transaction abort.
