Not to be fixed
Created: Mar 2, 2024
Updated: Apr 15, 2024
Resolved Date: Apr 15, 2024
Found In Version: 10.19.45.1
Severity: Standard
Applicable for: Wind River Linux LTS 19
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:
btrfs: remove BUG() after failure to insert delayed dir index item
Instead of calling BUG() when we fail to insert a delayed dir index item
into the delayed node's tree, we can just release all the resources we
have allocated/acquired before and return the error to the caller. This is
fine because all existing call chains undo anything they have done before
calling btrfs_insert_delayed_dir_index() or BUG_ON (when creating pending
snapshots in the transaction commit path).
So remove the BUG() call and do proper error handling.
This relates to a syzbot report linked below, but does not fix it because
it only prevents hitting a BUG(), it does not fix the issue where somehow
we attempt to use twice the same index number for different index items.
