Overview

CVE-2023-52569 is a medium-severity vulnerability. It was published on March 2, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
