Overview

CVE-2024-27069 is a medium-severity vulnerability. It was published on May 1, 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:

ovl: relax WARN_ON in ovl_verify_area()

syzbot hit an assertion in copy up data loop which looks like it is

the result of a lower file whose size is being changed underneath

overlayfs.

This type of use case is documented to cause undefined behavior, so

returning EIO error for the copy up makes sense, but it should not be

causing a WARN_ON assertion.

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.
