- Summary
- btrfs: abort transaction on unexpected eb generation at btrfs_copy_root()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: abort transaction on unexpected eb generation at btrfscopyroot()
If we find an unexpected generation for the extent buffer we are cloning at btrfscopyroot(), we just WARN_ON() and don't error out and abort the transaction, meaning we allow to persist metadata with an unexpected generation. Instead of warning only, abort the transaction and return -EUCLEAN.
