Overview

CVE-2025-39706 is a medium-severity vulnerability. It was published on September 5, 2025 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:

drm/amdkfd: Destroy KFD debugfs after destroy KFD wq

Since KFD proc content was moved to kernel debugfs, we can't destroy KFD

debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior

to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens

when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but

kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line

debugfs_remove_recursive(entry->proc_dentry);

tries to remove /sys/kernel/debug/kfd/proc/<pid> while

/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel

NULL pointer.

(cherry picked from commit 0333052d90683d88531558dcfdbf2525cc37c233)

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.
