Technical description

In the Linux kernel, the following vulnerability has been resolved:

dax: Fix dax_mapping_release() use after free

A CONFIG_DEBUG_KOBJECT_RELEASE test of removing a device-dax region

provider (like modprobe -r dax_hmem) yields:

kobject: 'mapping0' (ffff93eb460e8800): kobject_release, parent 0000000000000000 (delayed 2000)

needs to hold a reference that it drops

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.
